Automatic Mode Shift 36 V 300 mA LDO NO.EA-185-140724 OUTLINE The R1510S is a voltage regulator (LDO) IC with a volt age detector (VD) featuring 300mA output current that is developed with CMOS process technology. Each IC is equipped with a voltage detector and a regulator that can provide the maximum 36V of operating voltage. This device has ECO function, which achieves low-power consumption and high-speed transient response by switching the IC to low-power consumption mode at light load condition and switching to high-speed mode at heavy load condition. The switching point is internally fixed inside the IC. The IC switches from low-power consumption mode to high- speed mode when IOUT=12mA (Typ.), and switch from high-speed mode to low-power consumption mode when IOUT=3mA (Typ.). Each IC is composed of a reference voltage unit, an error amplifier, a resistor network for setting output voltage, an output current limit circuit for pr eventing overcurrent destruction, and a thermal shutdown circuit. The output voltage and the detector threshold are internally fixed inside the IC. The output voltage accuracy is ±1.6% and the detector th reshold accuracy is ±1.7%. The output voltage type is Nch open drain. The versions for the IC are selectable from A version (CE, V IN Detector), B version (SENSE Detector), C version (Release Delay Circuit, VIN Detector), and D version (Release Delay Circuit, VOUT Detector).

Therefore, please make sure to use a capacitor (C OUT) with 6.8µF or more. If the ESR value is large, the output may result in uns table, therefore, please make full evaluation on the temperature characteristics and the frequency characteristics. PCB Layout and GND Wiring The high impedances of VDD and GND could be a reason for the noise pickup and unstable operation. Therefore, make the impedances of V DD and GND as low as possible. A capacitor (C IN) with 0.1µF or more has to be connected between V DD pin and GND pin, and the wirings between t hem have to be short as possible. The capacitor (COUT) for phase compensation has to be connected between V OUT pin and GND pin, and the wirings between them have to be short as possible. CIN=0.1μF, COUT=6.8μF (Ceramic) Rpull-up=100kΩ

NO.EA-185-140724 OPERATION MANUAL Voltage Regulator (VR) Voltage Regulator (VR) operates within the input voltage range of 3.5V to 36V. The output voltage is adjustable within the range of 2.5V to 12V by 0.1V step. By changing the current value of the control circuit according to the load current, the supply current at the light load conditi on can be minimized and also be able to achieve high speed response. When the load current becomes 12mA (Typ.) or more, the control circuit switches to high-speed mode and when the load current becomes 3mA or lower, it switches to low-power consumption mode. Hysteresis is set for the output current between 3mA to 12mA (Typ.). These current values are internally fixed inside the IC. When the mode switching is caused by the load current change, the output voltage will be changed as the grap h below shows. The load current dependencies (Load Regulation) of output voltage in Electrical Characterist ics have been tested at the following points: 0.1mA, 7mA (Low-power consumption mode), 20mA, and 300mA. During the period of 100µsec immediately after High-speed mode is switched to Low-power consumption mode, the current value (IOUTH), which switches Low-power consumption mode back to High-speed mode, is increased 3 times. Therefore, during this time period, the IC can still operate with Low-power consumption mode even if the load current is between 12mA to 36mA (Typ.). R1510SxxxA can turn on and off the operation of VR by CE pin. Voltage Detector (VD) Voltage Detector (VD) operates within the input vo ltage range of 1.8V to 36V (R1510SxxxA/C/D) and 3.0V to 36V (R1510SxxxB). The detector threshold is adjustable in the range of 2.3V to 12V by 0.1V step. If the monitor voltage is lower than the detector threshold, DOUT outputs “L”. In the case of R1510SxxA/B, if the monitor voltage becomes more than the released voltage, DOUT outputs “H”. In the case of R1510SxxxC/D, if the monitor voltage becomes more than the released voltage, the capac itor of the release output delay time pin (C D) starts to get charged. DOUT output maintains “L” until CD reaches to the threshold value. Once C D value becomes more than the threshold value, DOUT outputs “H”. In the case of R1510SxxxC/D, if the monitor voltage becomes lower than the detector threshold, the capacitor of C D starts to get discharged. Therefore, if the monitor voltage becomes more than the released voltage without electrical dischar ge, the release output delay time afterwards becomes less than the existing release output delay time (tDELAY). 4.97 4.98 4.99 5.00 5.01 5.02 5.03 0 1 02 03 04 05 0 Output Current IOUT (mA) Output Voltage VOUT (V) From Low-power consumption Mode to High-speed Mode From High-speed Mode to Low-power consumption Mode

Similarly, if VIN voltage is raised from the less than the minimum operating voltage to the more than the release voltage, VIN momentarily passes through the unstable range (from 0V to the minimum operating voltage), therefore, DOUT may output “H” once.

NO.EA-185-140724 Release Output Delay Time The release output delay time (Power-on Reset Time (tDELAY)) of R1510SxxxC/D can be set by the capacitor of CD pin. The relationship between the capacitor capacitance and tDELAY is as shown in the following equation. tDELAY(s)=7.0×105×CD(F) The upper limit of the capacitance value for the C D pin capacitor is 1µF. The capacitor operates normally with more than 1µF; however, if the setting time (tDELAY) is set longer, the setting time differences could become bigger. Also, if the detect output delay time bec omes longer; the response of the VD output pin will be slow to make a momentary stop. If the VDD pin voltage is decreased with more than the through ra te as it is shown in the graph below, the IC does not operate normally. If there’s any possibility of this, please minimize the voltage fluctuation of V DD pin by using CIN. 0.01 0.1 100 0 1 2 3 4 5 6 7 8 9 10 11 12 Vpp (V) Inp ut Vol tag e Fal ling Ti me TF (μs The detector cannot maintain the detection. Input Voltage Falling Time tf (μs) VDD Vpp tf VDD Input Waveform Thermal Shutdown If the junction temperature (Tj) becomes more than 140°C(Typ.) due to the heat generation in the voltage regulator, the output driver will be turned off to protect the IC and the voltage regulator output will be turned off. If the junction temperature becomes less than 125°C(Typ.) , the output driver will be turned on and the voltage regulator output will be turned on. Unless the cause of the heat generation is not removed, the voltage regulator repeats turns on and off, so the output voltage will be a pulsing form. R1510SxxxD Voltage Setting The voltage detector (VD) of R1510SxxxD detects the output voltage drop of the voltage regulator (VR). If the VD release voltage is set to more than the VR output vo ltage, the VD will not be canceled even if the VR output voltage returns to the normal value after VD detected the output voltage drop of VR. To avoid this, there have to be voltage differences between the voltage regulator’s output voltage (V OUT) and the voltage detector’s release voltage (+VDET). Also, the following conditions have to be met. (VR Output Setting Voltage) x 0.964 > (VD Detect Setting Voltage) x1.03 x 1.075 In case of using the products with the VR output voltage and the VD detector threshold that is not met the above conditions, please make sure to give greater consideration on the system operation before use.
