1 / 13 page RT9167/A 1 DS9167/A-26 March 2007 www.richtek.com Pin Configurations Low-Noise, Fixed Output Voltage,300mA/500mA LDO Regulator Ordering Information (TOP VIEW) 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 1 μF 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.
