HIGH RIPPLE-REJECTION

LOW DROPOUT CMOS VOLTAGE REGULATOR

S-T111 Series

The S-T111 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. Compared with the voltage regulators using the

conventional CMOS process, a larger variety of

capacitors are available, including small ceramic

capacitors. A small SOT-23-5 package realizes high-

density mounting.

Features

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

• Output voltage:

• High-accuracy output voltage:

• Low dropout voltage:

• Low current consumption:

±1.0%

190 mV typ. (3.0 V output product, I_OUT= 100 mA)

During operation: 50 μA typ., 90 μA max.

During shutdown: 0.1 μA typ., 1.0 μA max.

150 mA output is possible (at V_IN≥ V_OUT(S)+ 1.0 V)^*1

Ensures long battery life.

• High peak current capability:

• Built-in ON/OFF circuit:

• Low ESR capacitor can be used: A ceramic capacitor of 0.1 μF or more can be used for the output

capacitor.

80 dB typ. (at 1.0 kHz)

Overcurrent of output transistor can be restricted.

SOT-23-5

• High ripple rejection:

• Built-in overcurrent protector:

• Small package:

• Lead-free products

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

Applications

• Power supply for battery-powered devices

• Power supply for personal communication devices

• Power supply for home electric/electronic appliances

• Power supply for cellular phones
