1 / 11 page RT9168/A 1 DS9168/A-15 March 2007 www.richtek.com Pin Configurations 200mA/500mA Fixed Output Voltage LDO Regulator Ordering Information (TOP VIEW) General Description The RT9168/A is a 200mA/500mA low dropout and micropower regulator suitable for portable applications. The output voltages range from 1.5V to 5.0V in 100mV increments and 2% accuracy. The RT9168/A is designed for use with very low ESR capacitors. The output remains stable even with a 1 μF ceramic output capacitor. The RT9168/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 current limiting and over temperature protection. The SOT-23-5 and SOP-8 packages are also available for larger power dissipation and design flexibility.
