RT9167/A
Low-Noise, Fixed Output Voltage, 200mA/500mA LDO Regulator
General Description
The RT9167/A is a 200mA/500mA low dropout and low noise micropower regulator suitable for portable applications. The output voltages range from 1.5V to 5.0V in 100mV increments and 2% accuracy. The RT9167/A is designed for use with very low ESR capacitors. The output remains stable even with 1µF ceramic output capacitor. The RT9167/A uses and 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-power devices. Other features include a reference bypass pin to improve low noise performance, current limiting, and over temperature protection.
Features
Stable with Low-ESR Output Capacitor Low Dropout Voltage (220mV and 200mA) Low Operation Current - 80µA Typical Shutdown Function Low Noise Output 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
