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 165
μ
A supply current (both
LDOs on) independent of load current and dropout
conditions. The SHDN1 and SHDN2 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.
