HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION S-1701 Series Rev.3.1_00 Seiko Instruments Inc. 34  Selection of Input and Output Capacitors (CIN, CL) The S-1701 Series requires an output capacitor between the VOUT pin and VSS pin for phase compensation. A ceramic capacitor with a capacitance of 1.0 μF or more provides a stable operation in all temperature ranges. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capac itor, the capacitance must be 1.0 μF or more, and the ESR must be 10 Ω or less. The output overshoot and undershoot valu es, which are transient response charac teristics, vary depending on the output capacitor value. The required capacitance value for the input capacitor differs depending on the application. The recommended application values are C IN ≥ 1.0 μF and CL ≥ 1.0 μF, however, perform thorough evaluation using the actual device, including evaluation of temperature characteristics.  Explanation of Terms Regulator block 1. Low dropout voltage regulator This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor. 2. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1701 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR is 10 Ω or less can be used. 3. Output voltage (V OUT) The accuracy of the output voltage is ensured at ±1.0% under the specified conditions of fixed input voltage *1, fixed output current, and fixed temperature. *1. Differs depending on the product. Caution If the above conditions change, the output voltage value ma y vary and exceed the accuracy range of the output voltage. Refer to “  Electrical Characteristics” and “ Characteristics (Typical Data)” for details. 4. Line regulation  ΔVOUT1 ΔVIN•VOUT Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output voltage changes due to a change in the input voltage with the output current remaining unchanged. 5. Load regulation ( ΔVOUT2) Indicates the dependency of the output voltage on the output current. That is , the values show how much the output voltage changes due to a change in the output current with the input voltage remaining unchanged. 6. Dropout voltage (V drop) Indicates the difference between input voltage (V IN1) and the output voltage when; decreasing input voltage (V IN) gradually until the output voltage has dropped ou t to the value of 98% of output voltage (V OUT3), which is at V IN = VOUT(S) + 1.0 V.

Detection voltage ( −VDET), release voltage (+VDET) The detection voltage ( −VDET) is the voltage at which the output switches to low. The de tection voltage varies slightly among products of the same specific ation. The variation of detection vo ltage between the specified minimum ( −VDET) Min. and the maximum (−VDET) Max. is called the detection voltage range (refer to Figure 29). This means that some products have 2.97 V for −VDET and some have 3.03 V. The release voltage ( +VDET) is the voltage at which the ou tput switches to high. The release voltage varies slightly among products of the same specificat ion. The variation of release voltages between the specified minimum ( +VDET) Min. and the maximum (+VDET) Max. is called the release voltage range (refer to Figure 30). This means that some products have 3.059 V for +VDET and some have 3.242 V. Detection voltage Detection voltage range V IN (−VDET) Min. (−VDET) Max.

Hysteresis width (V HYS) The hysteresis width is the voltage difference between the detection voltage and the release voltage. The existence of the hysteresis width prevents malfunction caused by noise on the input voltage. 3. Delay time (t D) The delay time is a time internally measured from the in stant at which the voltage input to the VDD pin exceeds the release voltage (+VDET) to the point at which the output of the OUT pin inverts.

The through-type current flows at a frequency of 20 kHz during the release delay time since the internal logic circuit operates.

ON/OFF pin (S-1701 Series A/ B/C/D/E/F/G/H/J/K/L/M types) This pin starts and stops the regulator. When the ON/OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in P-channel MOS FET output transistor between the VIN pin and the VOUT pin is turned off, reducing current consumption significantly. At this time, the current consumption equals that consumed by the detector block, because the internal circuits of the detector are operat ing. The VOUT pin becomes the V SS level due to the internally divided resistance of several hundreds kΩ between the VOUT pin and the VSS pin. The structure of the ON/OFF pin is as shown in Figure 35. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating status. In addition, note that the current consumption increases if a voltage of 0.3 V to VIN − 0.3 V is applied to the ON/OFF pin. When not using t he ON/OFF pin, connect it as follows according to the product type. S-1701 Series A/B/C/D/E/F types: Connect to the VIN pin. S-1701 Series G/H/J/K/L/M types: Connect to the VSS pin.

Figure 37 Operation 2. Delay circuit The delay circuit delays the output signal from the time when the SENSE voltage (V SENSE) exceeds the release voltage (+VDET) when VSENSE is turned on (refer to point B in Figure 37 ). The output signal is not delayed when V SENSE goes below the detection voltage (−VDET) (refer to point A in Figure 37). The delay time (t D) is a fixed value that is dete rmined by a counter and a built-in clock generator which consists of constant current and a capacitor. 3. Delay circuit output voltage detection ty pe (S-1701 Series D/E/F/K/L/M/U/V/W types) If the input voltage or load current changes transiently, an undershoot or overshoot occurs in the output voltage of the regulator. In the product types in which the output voltage of the regulator is detected by the detector, if the output voltage is the detection voltage or lower due to the undershoot, the detector operates and a reset signal may be output. To prevent this, set the value of the input-and-out put capacitor of a regulator so that the undershoot is the minimum value or set a voltage range that allows the difference between the output voltage and detection voltage to be equal to or greater than the undershoot.

HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION S-1701 Series Rev.3.1_00 Seiko Instruments Inc. 44  Explanation for Each Type 1. S-1701 Series A/B/C types The S-1701 Series A/B/C types provide a regulator block sta ndby mode realized by an ON/OFF function that is active high. The internal circuit of the detec tor operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VIN pin in the internal circuit of the detecto r block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (A: No delay (60 μs), B: 50 ms, C: 100 ms). The power supply is shared by the regulator block and detector block and supplied from t he VIN pin, so care must be taken concerning VIN pin input impedance*1. 2. S-1701 Series D/E/F types The S-1701 Series D/E/F types provide a regulator block standby mode realized by an ON/OFF function that is active high. The internal circuit of the detec tor operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VOUT pi n, which is an output of the regulator, in the intern al circuit of the detector block, so the output volt age of the regulator (V OUT) is monitored and a reset signal is output from the VDOUT pin *2. The built-in counter timer allows selection of the release delay time from three settings (D: No delay (60 μs), E: 50 ms, F: 100 ms). The power supply is shared by the regulator block and detector block and supplied from t he VIN pin, so care must be taken concerning the VIN pin input impedance*1. 3. S-1701 Series G/H/J types The S-1701 Series G/H/J types provide a regulator block standby mode realized by an ON/OFF function that is active low. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VIN pin in the internal circuit of the detecto r block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (G: No delay (60 μs), H: 50 ms, J: 100 ms). The power supply is shared by the regulator block and detector block and supplied from t he VIN pin, so care must be taken concerning the VIN pin input impedance *1. 4. S-1701 Series K/L/M types The S-1701 Series K/L/M types provide a regulator block sta ndby mode realized by an ON/OFF function that is active low. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VOUT pi n, which is an output of the regulator in the internal circuit of the detector block, so the output volt age of the regulator (V OUT) is monitored and a reset signal is output from the VDOUT pin *2. The built-in counter timer allows selection of the release delay time from three settings (K: No delay (60 μs), L: 50 ms, M: 100 ms). The power supply is shared by the regulator block and detector block and supplied from t he VIN pin, so care must be taken concerning the VIN pin input impedance *1.

HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.3.1_00 S-1701 Series Seiko Instruments Inc. 45 5. S-1701 Series N/P/Q types The S-1701 Series N/P/Q types do not provide an ON/OFF func tion because the ON/OFF pin is connected to the VIN pin in the circuit. The detector block features the external SENSE pin, which allows monitoring of other power supplies. The SENSE pin is configured only by a resistor, so instantaneous current such as through-type current does not flow through this pin. This allows precise monitoring of the input power supply by connecting the SENSE pin to the input power supply even when a resistor (R IN) is connected between the input power supply and the VIN pin. The built-in counter timer allows selection of the release delay time from three settings (N: No delay (60 μs), P: 50 ms, Q: 100 ms). The power supply is shared by the regulator block and detect or block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 6. S-1701 Series R/S/T types In the S-1701 Series R/S/T types, the VDOU T pin, which is the output pin of the detector, is connected to the ON/OFF pin of the regulator in the circuit. This allows setting of the regulator to the standby m ode at the same time as the VDOUT pin outputs a RESET signal. The detector block features an external SENSE pin, which a llows monitoring of other power supplies. The SENSE pin is configured only by a resistor, so instantaneous current such as through-type current does not flow through this pin. This allows precise monitoring of the input power supply by connecting the SENSE pin to the input power supply even when a resistor (R IN) is connected between the input power supply and the VIN pin. The built-in counter timer allows selection of the release delay time from three settings (R: No delay (60 μs), S: 50 ms, T: 100 ms). The power supply is shared by the regulator block and detect or block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 7. S-1701 Series U/V/W types The S-1701 Series U/V/W types do not provide an ON/OFF function because the ON/OFF pi n is connected to the VIN pin in the circuit. The SENSE pin is connected to the VOUT pin, which is an out put pin of the regulator, in the internal circuit of the detector block, so the output voltage of the regulator (V OUT) is monitored and a reset signal is output from the VDOUT pin*2. The built-in counter timer allows selection of the release delay time from three settings (U: No delay (60 μs), V: 50 ms, W: 100 ms). The power supply is shared by the regulator block and detect or block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 8. S-1701 Series X/Y/Z types The S-1701 Series X/Y/Z types do not provide an ON/OFF f unction because the ON/OFF pin is connected to the VIN pin in the circuit. The SENSE pin is connected to the VIN pin in the internal circuit of the detecto r block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (X: No delay (60 μs), Y: 50 ms, Z: 100 ms). The power supply is shared by the regulator block and detector block and supplied from t he VIN pin, so care must be taken concerning the VIN pin input impedance*1.

HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION S-1701 Series Rev.3.1_00 Seiko Instruments Inc. 46 *1. In S-1701 series, when connecting the resistance R IN between an input power supply pin and a VIN pin, and defining the current which flows into R IN as IIN, VIN pin voltage falls by Δ VIN = IIN×RIN at the time of overload, and changes by ΔVIN = I IN×RIN at the time of load change. Thereby, keep in mind that phenom ena, such as output voltage falls and an output oscillation, occur. *2. If the input voltage or load current changes transiently, an undershoot or overshoot occurs in the output voltage of the regulator. In the product types in which the output voltage of the regulator is detected by the detector, if the output voltage is the detection voltage or lower due to the undershoot, the detector operates and a reset signal may be output. To prevent this, set the value of the input-and-output capacitor of a regulator so that the undershoot is the minimum value or set a voltage range th at allows the difference between the output voltage and detection voltage to be equal to or greater than the undershoot.

HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.3.1_00 S-1701 Series Seiko Instruments Inc. 47  Precautions

• Wiring patterns for the VIN pin, the VOUT pin and GND s hould be designed so that the impedance is low. When mounting an output capacitor between the VOUT pin and the VSS pin (C L) and a capacitor for stabilizing the input between the VIN pin and the VSS pin (C IN), the distance from the capacitors to these pins should be as short as possible.
• Note that generally the output voltage may increase when a series regulator is used at low load current (1.0 mA or less).
• Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for the S-1701 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (C IN): 1.0 μF or more Output capacitor (C L): 1.0 μF or more Equivalent series resistance (ESR): 10 Ω or less
• The voltage regulator may oscillate when the impedance of t he power supply is high and the input capacitance is small or an input capacitor is not connected.
• Overshoot may occur in the out put voltage momentarily if t he voltage is rapidly raised at power-on or when the power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual device.
• The application conditions for the input voltage, the output voltage, and the load current should not exceed the package power dissipation.
• Do not apply an electrostatic discharge to this IC that ex ceeds the performance ratings of the built-in electrostatic protection circuit.
• In determining the output current, attention should be paid to the output curr ent value specified in Tables 26 to 31 in “ Electrical Characteristics” and footnote *7 of the table.
• SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party.
