HIGH RIPPLE-REJECTION LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.4.1_00
The S-1165 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and
low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in
overcurrent protection circuit prevents the load current from exceeding the current capacity of the output
transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realizes high-density
mounting.
