100mA, 4µA QUIESCENT

CURRENT CMOS LDO

REGULATOR

DESCRIPTION

The UTC LR1101 series are ultra-low quiescent current CMOS

LDO (Low Dropout Voltage). Designed for battery-powered system,

the low 4μA quiescent current makes it an ideal choice. The Range

of the output voltage is from 1.5V ~ 5V with 0.1V per step. And the

max output current is 100mA.

Wide range of available output fits most of applications. Built-in

output current-limiting provide maximal protection against any fault

conditions.

FEATURES

* 450mV typically dropout at 100mA

* Ultra-low quiescent current: 4μA

* Wide operating voltage ranges: 2V ~ 6V

* Thermal current limiting protection

* For stability only 1μF output capacitor is required

* High power supply rejection ratio
