200mA/500mA Fixed Output Voltage LDO Regulator

RT9168/RT9168A

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 1μF 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.

Applications

Cellular Telephones
Laptop, Notebook, and Palmtop Computers
Battery-powered Equipment
Hand-held Equipment
