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 +5.5V input.
The RT9182 uses an internal PMOS as the pass device,
which consumes 165uA 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.
