The S-1165 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, 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 protector prevents the load current from exceeding the current capacitance of

the output transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package

realizes high-density mounting.
