RT9182ACE

Dual, Low-Noise, 200mA LDO Regulator

Richtek Technology 

Preliminary

RT9182

Dual, Low-Noise, 200mA LDO Regulator

General Description

The RT9182 is a dual-channel, low noise, and low

dropout regulator supplying up to 200mA current at

each channel. The output voltage ranges from 1.5V

to 3.3V in 100mV increments and 2% accuracy by

operating from a +2.7V to +6.5V input.

The RT9182 uses an internal PMOS as the pass

device, which consumes 165µA supply current (both

LDOs on) independent of load current and dropout

conditions. The SHDN pin controls both outputs

simultaneously and consumes nearly zero operation

current in the disable mode making the IC suitable

for battery-power devices. Other features include a

reference voltage bypass pin to improve low noise

performance, current limiting, and over temperature

protection.
