uP8808P/Q Ultra Low Noise, Fast Response, High PSRR 1.5A Low Dropout Linear Regulator General Description The uP8808P/Q is an ultra low noise, fast response, high power supply rejection ratio (PSRR) low dropout regulator specifically designed to continuously deliver up to 1.5A output current. Designed with a P-channel MOSFET series pass transistor, the uP8808P/Q yields extremely low dropout voltage (e.g. 240mV at 1A) and maintains very low ground current (200uA). The uP8808P/Q is designed and optimized to work with low-value, low-cost ceramic capacitors. Only a 4.7uF ceramic output capacitor is required for stable operation for any load conditions, ideal suitable for portable RF and wireless applications where PCB size are specially concerned.
