Low-Noise, Fixed Output Voltage,
200mA/500mA LDO Regulator
General Description
The RT9167/A is a 200mA/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 1
μ
F
ceramic output capacitor.
The RT9167/A uses and 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-power devices. Other features
include a reference bypass pin to improve low noise
performance, current limiting, and over temperature
protection.
