RT9169/H
100mA, 4μA Quiescent Current CMOS LDO Regulator
General Description
Features
The RT9169/H 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.
