www.sii-ic.com HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR © Seiko Instruments Inc., 2008-2015 Rev.2.2_00 Seiko Instruments Inc. 1 The S-1135 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low dropout voltage, the high-accuracy output voltage and the low current consumption (300 mA output current). A 1.0 μF small ceramic capacitor can be used. It operates with low current consumption of 45 μA typ. The overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. The ON / OFF circuit ensures longer battery life. Various capacitors, also small ceramic capacitors, can be used for this IC more than for the conventional regulator ICs which have CMOS technology. Furthermore, a small SOT-89-5, SOT-23-5, and HSNT-6A packages realize high-density mounting.  Features

C IN is a capacitor for stabilizing the input. *2. A ceramic capacitor of 1.0 μF or more can be used as CL. Figure 18 Caution The above connection diag ram and constant will not guarantee successful operation. Perform thorough evaluation using the actual application to set the constant.  Condition of Application Input capacitor (CIN) : 1.0 μF or more Output capacitor (CL) : 1.0 μF or more Caution Generally a series regulator may cause oscillation, depending on the selection of external parts. Confirm that no oscillation occurs in the application for which the above capacitors are used.  Selection of Input and Output Capacitors (CIN, CL) The S-1135 Series requires an output c apacitor between the VOUT and VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output c apacitance of 1.0 μF or more over the ent ire temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capac itance must be 1.0 μF or more. The value of the output ov ershoot or undershoot transient response varies depending on the value of the output capacitor. The required capacitance of the input capacitor differs depending on the application. The recommended capacitance for an application is C IN ≥ 1.0 μF, C L ≥ 1.0 μF; however, when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.2.2_00 S-1135 Series Seiko Instruments Inc. 21 3. ON / OFF pin 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 and VOUT pins is turned off, reducing current consumption significantly. Since the S-1135 Series A / B / E / F type has a built-in discharge shunt circuit to disc harge the output capacitance, the VOUT pin is forcibly set to V SS level. In the S-1135 Series C / D / G / H type, the VOUT pin is set to V SS level through several hundred k Ω internal divided resistors between the VO UT and VSS pins. Note that the current consumption increases when a voltage of 0.3 V to 1.0 V (Ta = 25°C) is applied to the ON / OFF pin. The ON / OFF pin is configured as shown in Figures 21 and 22. In the S-1135 Series A / C / E / G type, the ON / OFF pin is internally pulled up to the VIN pin or pulled down to the VSS pin in the floating status, so the VOUT pin is set to the V SS level. In the S-1135 Series B / D / F / H type, t he ON / OFF pin is not internally pulled up or pulled down, so do not use the ON / OFF pin in the floating status. When not using t he ON / OFF pin, connect it to the VIN pin in the product B / D type, and connect it to the VSS pin in the F / H type. Table 11 Product Type ON / OFF Pin Internal Circuit VOUT Pin Voltage Current Consumption A / B / C / D “H”: ON Operate Set value ISS1 A / B / C / D “L”: OFF Stop VSS level ISS2 E / F / G / H “H”: OFF Stop VSS level ISS2 E / F / G / H “L”: ON Operate Set value ISS1 *1. Note that the IC’s current cons umption increases as much as curr ent flows into the pull-up / pull-down resistor when; the ON / OFF pin is connected to the VIN pin in the A / C type, the ON / OFF pin is connected to the VSS pin in the E / G type (Refer to Figure 21).

Discharge shunt function (S-1135 Series A / B / E / F type) The S-1135 Series A / B / E / F type has a built-in dischar ge shunt circuit to dischar ge the output c apacitance. When the ON / OFF pin is set to OFF level, turns the output transistor off, and turns the discharge shunt circuit on so that the output c apacitor discharges. These types allo w the VOUT pin to reach the V SS level faster than the S-1135 Series C / D / G / H type that does not have a discharge shunt circuit.

HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.2.2_00 S-1135 Series Seiko Instruments Inc. 23 5. Overcurrent protection circuit The S-1135 Series has an overcurrent protection circuit having the characteristics shown in “1. Output Voltage vs. Output Current (When Load Current Increases) (Ta = 25 °C)” in “ Characteristics (Typical Data) ”, in order to protect the output transistor against an excessive output current and shor t circuiting between the VOUT and VSS pins. The current when the output pin is short-circuited (Ishort) is internally set at approx. 100 mA (typ.), and the normal value is restored for the output voltage, if releasing a short circuit once. Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps short circuiting inside, pay attention to the conditions of input voltage and load current so that, under the usage conditions including short circui t, the loss of the IC will not exceed power dissipation of the package. 6. Pull-down / pull-up resistor (S-1135 Series A / C / E / G type) In the S-1135 Series A / C / E / G type, the ON / OFF pin is internally pulled up to the VIN pin or pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS level. Note that the IC’s current consumption increases as much as current flows into the pull-up / pull-down resistor of 2.2 MΩ (typ.) when; the ON / OFF pin is connected to the VIN pin in the A / C type, the ON / OFF pin is connected to the VSS pin in the E / G type.

HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1135 Series Rev.2.2_00 Seiko Instruments Inc. 24  Precautions

• Wiring patterns for the VIN pin, the VOUT pin and G ND should be designed so that the impedance is low. When mounting an output c apacitor between the VOUT and VSS pins (C L) and a capacitor for stabilizing the input between the VIN and VSS pins (CIN), 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).
• Note that generally the out put voltage may increase due to the leakage curr ent from an output dr iver when a series regulator is used at high temperature.
• Generally a series regulator may cause oscillation, depending on the selecti on of external parts. The following conditions are recommended for the S-1135 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Refer to “ 5. Example of Equivalent Series Resistance vs. Output Current Characteristics (Ta = 25 °C)” in “ Reference Data” for the equivalent series resistance (RESR) of the output capacitor. Input capacitor (C IN) : 1.0 μF or more Output capacitor (C L) : 1.0 μF or more
• The voltage regulator may oscillate w hen the impedance of the power supply is high and the input capacitance is small or an input capacitor is not connected.
• If the output capacitance is sm all, power supply’s fluctuation and the characteristics of l oad fluctuation become worse. Sufficiently evaluate the output voltage’s fluctuation with the actual device.
• Overshoot may occur in the output volt age momentarily if the 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 i nput voltage, the output voltage, and the load curr ent 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 out put current value specified in Table 10 in “ Electrical Characteristics” and footnote *5 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.
