RT9167/A
Low-Noise, Fixed Output Voltage,300mA/500mA LDO Regulator
General Description
Features
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 5V
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 P-MOSFET 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.
