Preliminary

RT9169

100mA, 4µµµµA Quiescent Current CMOS LDO Regulator

General Description

The RT9169 series are 100mA ultra-low quiescent

current CMOS low dropout (LDO) regulator designed

for battery-powered equipments. The output voltages

range from 1.2V to 5V with 0.1V per step.

The other features include 4µA ultra-low quiescent,

low dropout voltage, high output accuracy, current

limiting protection, and high ripple rejection ratio.
