REVERSE CURRENT PROTECTION
CMOS VOLTAGE REGULATOR
Rev.1.2
_02
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
A
typ., it has high ripple-rejection of 70 dB typ., and a ceramic capacitor of 1.0
F
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
A
max. Therefore, IC protection diode is not needed.
