ABLIC S-13R1G26-M5T1U3

The S-13R1 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 150 mA output current, which has low dropout voltage, high-accuracy output voltage and low current consumption. Even with low current consumption of 5 μA typ., it has high ripple-rejection of 70 dB typ., and a ceramic capacitor of 1.0 μF or more can be used as the input and output capacitors. The S-13R1 Series includes an overcurrent protection circuit that prevents the load current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that prevents damage because of overheating. Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be controlled as the small value 0.09 μA max. Therefore, IC protection diode is not needed.
