RT9167/A
Low-Noise, Fixed Output Voltage,300mA/500mA LDO Regulator
General Description
The RT9167/A is a 300mA/500mA low dropout and low
noise micropower regulator suitable for portable
applications. The output voltages range from 1.5V to 5.0V
in 100mV increments and 2% accuracy. The RT9167/A is
designed for use with very low ESR capacitors. The output
remains stable even with 1μF ceramic output capacitor.
The RT9167/A uses
an internal PMOS as the pass device,
which does not cause extra GND current in heavy load
and dropout conditions. The shutdown mode of nearly zero
operation current makes the IC suitable for battery-powered
devices. Other features include a reference bypass pin to
improve low noise performance, current limiting, and over
temperature protection.
