Package

Seiko Instruments Inc.

The S-1111/1121 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

realize high-density mounting. The lineup includes

the S-1111 and S-1121 Series, which differ in pin

configuration.
