uP8805P

Ultra Low Noise, Fast Response, High PSRR

700mΩ Low 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 (V_IN-

Dropout Voltage)

Over-Temperature Protection

RoHS Compliant and Halogen Free

Applications

Cellular and Cordless Phones
