uP8804P
Ultra Low Noise, Fast Response, High PSRR
700mΩ Low Dropout Linear Regulator
Features
General Description
The uP8804P is an ultra low noise, fast response, high Wide Input Voltage Range from 2.4 to 5.5V
power supply rejection ratio (PSRR) low dropout regulator
specifically designed to continuously deliver up to 500mA
output current.Designed with a P-channel MOSFET series
pass transistor, the uP8804P yields extremely low dropout
voltage (e.g. 210mV at 300mA, 350mV at 500mA) and
maintains very low ground current (70uA).
Ultra Low Dropout Voltage: 210mV @ 300mA
High Power Supply Rejection Ratio
70dB at 1kHz
40dB at 100kHz
Ultra Low Output Noise Voltage 100uV(RMS)
Ultra Fast Response in Line/Load Transient
Stable with 1uF Ceramic Output Capacitor
Low Ground Current: 70uA
The uP8804P does not require a bypass capacitor, hence
achieving the smallest PCB area. This device reduces
output voltage noise to 100uV(RMS) and improves PSRR to
40dB at 100kHz.
Low Shutdown Current: < 1uA
The uP8804P is designed and optimized to work with low-
value, low-cost ceramic capacitors. Only a 1uF ceramic
output capacitor is required for stable operation for any
load conditions.
Foldback Output Current Limit
High Output Accuracy
1.0% Initial Accuracy
Other features include foldback overcurrent protection,
quick soft start, and overtemperature protection. The
uP8804P is available in adjustable or fixed output voltage
from 0.8V to 3.3V with 0.1V per step. The device comes
in SC70-5/6L, TSOT23-5L packages.
