The uP0108 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 uP0108 yields extremely low dropout voltage (e.g. 300mV at 300mA).

The uP0108 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 uP0108 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 overtemperature protection. The uP0108 is available in adjustable or fixed output voltage from 0.8V to 4.75V with 0.1V per step. The device comes in SC70-5L, SC82-4L, SOT23-5L, and WDFN1.6x1.6-6L packages.
