HIGH RIPPLE-REJECTION LOW DROPOUT
CMOS VOLTAGE REGULATOR
S-1111/1121 Series
www.datasheet4u.com
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.
