The uP8806J is an ultra low noise, fast response, high power supply rejection ratio (PSRR) low dropout regulator specifically designed to continuously deliver up to 300mA output current. Designed with a P-channel MOSFET series pass transistor, the uP8806J yields extremely low dropout voltage (e.g. 300mV at 300mA).The uP8806J does not require a bypass capacitor, hence achieving the smallest PCB area. This device reduces output voltage noise under 70uV(RMS) and improves PSRR to 40dB at 100kHz.The uP8806J is designed and optimized to work with lowvalue, low-cost ceramic capacitors. Only a 1uF 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 uP8806J is available in fixed output voltage from 0.8V to 4.75V with 0.1V per step.

The device comes in UTDFN1x1 – 4L package.
