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.

1.5 V to 5.5 V, selectable in 0.1 V steps.
±1.0%
200 mV typ. (3.0 V output product, IOUT = 100 mA)
During operation: 35 μA typ., 65 μA max.
During shutdown: 0.1 μA typ., 1.0 μA max.
150 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1
Ensures long battery life.
70 dB typ. (at 1.0 kHz)
Overcurrent of output transistor can be restricted.
SOT-23-5
*1. Attention should be paid to the power dissipation of the package when the output current is large.
