uP8808
Ultra Low Noise, Fast Response, High PSRR
1A Low Dropout Linear Regulator
Features
General Description
The uP8808 is an ultra low noise, fast response, high power Wide Input Voltage Range from 2.5 to 5.5V
supply rejection ratio (PSRR) low dropout regulator
specifically designed to continuously deliver up to 1A output
current. Designed with a P-channel MOSFET series pass
transistor, the uP8808 yields extremely low dropout voltage
(e.g. 240mV at 1A) and maintains very low ground current
(200uA).
Ultra Low Dropout Voltage: 240mV @ 1A
High Power Supply Rejection Ratio
60dB at 100Hz
40dB at 100kHz
Ultra Low Output Noise Voltage: 100uV(RMS)
Ultra Fast Response to Line/Load Transient
Low Ground Current: 200uA
The uP8808 is designed and optimized to work with low-
value, low-cost ceramic capacitors. Only a 10uF ceramic
output capacitor is required for stable operation for any load
conditions, ideal suitable for portable RF and wireless
applications where PCB size are specially concerned. A
bypass pin is provided to reduce output noise voltage and
improve PSRR to 40dB at 100kHz.
Low Shutdown Current: < 1uA
Foldback Output Current Limit
High Output Accuracy
1.5% Initial Accuracy
Other features include foldback overcurrent protection, quick
soft start, and overtemperature protection. The uP8808 is
available in fixed output voltage from 0.8V to 3.3V with
0.1V per step. The device comes in PSOP-8L, SOT23-5L,
TSOT223-3L, WDFN3x3-8Land VQFN5x5-24L packages.
Fixed Output Voltages: 0.8V to 3.3V with 0.1V
