RT9168A 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 1F 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 batterypowered 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.
