uP8808 Datasheet | uPI Semiconductor

Description The u P8808 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 u P8808 yields extremely low dropout voltage (e.g. 240m V at 1A) and maintains very low ground current (200u A). The u P8808 is designed and optimized to work with lowvalue, low-cost ceramic capacitors. Only a 10u F 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 40d B at 100k Hz. Other features include foldback overcurrent protection, quick soft start, and overtemperature protection. The u P8808 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.
