uP8806 Ultra Low Noise, Fast Response, High PSRR 300/500mA Low Dropout Linear Regulator General Description The uP8806 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 uP8806 yields extremely low dropout voltage (e.g. 300mV at 300mA). The uP8806 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 uP8806 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.
