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.
Features
Stable with Low-ESR Output Capacitor Low Dropout Voltage (220mV at 200mA) Low Operation Current - 80µA Typical Shutdown Function Low Temperature Coefficient Current and Thermal Limiting Custom Voltage Available SOT-25 and SOP-8 Packages
Applications
Cellular Telephones Laptop, Notebook, and Palmtop Computers Battery-powered Equipment Hand-held Equipment
