RT9169
100mA, 4µA Quiescent Current CMOS LDO Regulator
General Description
Features
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.
z Ultra-Low Quiescent Current: 4µA
z Low Dropout: 450mV at 100mA
z Wide Operating Voltage Ranges: 2V~6V
z Current Limiting Protection
z Only 1µF Output Capacitor Required for
Stability
z High Power Supply Rejection Ratio
The other features include 4µA ultra-low quiescent,
low dropout voltage, high output accuracy, current
limiting protection, and high ripple rejection ratio.
Applications
Ordering Information
z Battery-Powered Equipment
z Palmtops, Notebook Computers
z Hand-held Instruments
z PCMCIA Cards

Application Information
A 1µF (or larger) capacitor is recommended between
VOUT and GND for stability. The part may oscillate
without the capacitor. Any type of capacitor can be
used, but not Aluminum electrolytes when operating
below –25°C. The capacitance may be increased
without limit.
A 1µF capacitor (or larger) should be placed between
VIN to GND.
