uP8807 Datasheet | uPI Semiconductor

Description The u P8807 is a pact fast response low dropout regulator specifically designed to continuously deliver up to 600m A output current. Designed with a P-channel MOSFET series pass transistor, the u P8807 yields extremely low dropout voltage (e.g. 300m V at 600m A) and maintains very low quiescent current (70u A). The u P8807 does not require a bypass capacitor, hence achieving the smallest PCB area. The u P8807 is designed and optimized to work with low-value, low-cost ceramic capacitors. Only a 1u F ceramic output capacitor is required for stable operation for any load conditions. Other features include foldback overcurrent protection, quick soft start, and over temperature protection. The u P8807 is available in fixed output voltage from 0.8V to 3.3V with 0.1V per step or as an adjustable device with a 0.8V reference voltage. The device es in various packages.
