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 +5.5V input.

The RT9182 uses an internal PMOS as the pass device,

which consumes 165 A supply current (both LDOs on)

independent of load current and dropout conditions. The

EN1 and EN2 pins control each output respectively. When

both outputs shutdown simultaneously, the chip will be

turn off and consumes nearly zero operation current

which is suitable for battery-power devices. Other

features include a current limiting, and over temperature

protection.
