RT9168/A
200mA/500mA Fixed Output Voltage LDO Regulator
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
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 SOP-8 and SOT-25 packages are
also available for larger power dissipation and
design flexibility.
