uP8808 Ultra Low Noise, Fast Response, High PSRR 1A Low Dropout Linear Regulator General Description The uP8808 is an ultra low noise, fast response, high power supply rejection ratio (PSRR) low dropout regulator specifically designed to continuously deliver up to 1A output current. Designed with a P-channel MOSFET series pass transistor, the uP8808 yields extremely low dropout voltage (e.g. 240mV at 1A) and maintains very low ground current (200uA). The uP8808 is designed and optimized to work with lowvalue, low-cost ceramic capacitors. Only a 10uF 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. A bypass pin is provided to reduce output noise voltage and improve PSRR to 40dB at 100kHz. Other Features include foldback overcurrent protection, quick soft start, and overtemperature protection. The uP8808 is available in fixed output voltage from 0.8V to 3.3V with 0.1V per step. The device es in PSOP-8L, SOT23-5L, TSOT223-3L, WDFN3x3-8L and VQFN5x5-24L packages.
