HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT

CMOS VOLTAGE REGULATOR

S-1131 Series

The S-1131 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 small SOT-89-3, SOT-89-5

and 6-Pin HSON(A) packages realize high-density

mounting.

1.5 V to 5.5 V, selectable in 0.1 V steps.

±1.0%

250 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.

300 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-89-3, SOT-89-5, 6-Pin HSON(A)

*1. Attention should be paid to the power dissipation of the package when the output current is large.

„ Applications
