RT9169/H
100mA, 4μA Quiescent Current CMOS LDO Regulator
General Description
Features
z Ultra-Low Quiescent Current: 4μA
z Low Dropout: 450mV at 100mA
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.
z Wide Operating Voltage Ranges: 2V to 6V
z Current Limiting Protection
z Only 1μF Output Capacitor Required for Stability
z High Power Supply Rejection Ratio
z RoHS Compliant and 100% Lead (Pb)-Free
The other features include 4μA ultra-low quiescent, low
dropout voltage, high output accuracy, current limiting
protection, and high ripple rejection ratio.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is highly recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
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 notAluminum 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.
