uP8805P  
Ultra Low Noise, Fast Response, High PSRR  
700mLow Dropout Linear Regulator  
Features  
General Description  
The uP8805P 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 uP8805P yields extremely low dropout  
voltage (e.g. 180mV at 300mA, 300mV at 500mA) and  
maintains very low ground current.  
† Ultra Low Dropout Voltage: 180mV @ 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 uP8805P 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 uP8805P 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

1.5% Initial Accuracy  
Other features include foldback overcurrent protection, quick  
soft start, and overtemperature protection. The uP8805P  
is available in adjustable voltage from 0.8V to 3.3V with  
0.1V per step. The device comes in SOT23 - 5L and  
TSOT23-5L packages.  
Adjustable Output Voltage from 0.8V to (VIN -  
Dropout Voltage)  
† Over-Temperature Protection  
† RoHS Compliant and Halogen Free  
Applications  
† Cellular and Cordless Phones  
† Bluetooth Portable Radios and Accessaries  
† Battery-Powered Equipment  
† Laptop, Palmtops, Notebook Computers  
† Hand-Held Instruments  
† PCMCIA Cards  
† Portable Information Appliances
