RT9168 datasheet



The RT9168 / RT9168A 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 ncrements and 2% accuracy. The RT9168/A is designed or use with very low ESR capacitors. The output remains stable even with a 1μF ceramic output capacitor.

The devices 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.
