RT9177/A
Ultra-Low-Noise 200mA/500mA LDO Regulator
General Description
Features
The RT9177/A is a 200mA/500mA low dropout and low noise micro-power regulator suitable for portable RF applications. The output voltage accuracy is within ±2% and range from 2.4V to 3.2V in 100mV increments could be selected. It is designed for using very low ESR output capacitor. Its output remains stable even when using a 1μF ceramic as its output capacitor.
With an internal PMOS as the pass device, it does not need extra GND current in heavy load and dropout conditions. In shutdown mode, nearly zero operation current makes the IC suitable for battery-power devices. Other features including current limiting and over temperature protection.
