400-mA MULTI-INPUT LOW-DROPOUT REGULATOR WITH DUAL

OUTPUT POWER MANAGEMENT

Features

Description

z Complete Power Management

z Automatic Input Voltage Selection

The AAT1205 is a multi-input low-dropout

regulator (LDO) specially designed for LAN cards.

It provides advanced dual constant output supply

3.3V & 2.5V at the output capable of driving a

400-mA load. The output (OUT25) can be

disabled by connecting EN25 pin to GND.

The AAT1205 is equipped with dual regulated

power output for systems with multiple input

sources and require dual constant voltage source

with a low-dropout voltage. This is an intelligent

power source selection device with a low-dropout

regulator for either VCC50 or VSB50 inputs, and

a low-resistance bypass switch for the AUX33

input.

Pin Configuration

TOP VIEW

The AAT1205 allows transitions to progress

smoothly from one input supply to another without

generating a glitch outside of the specified range

of 3.3V & 2.5V output. Furthermore, this device

has an incorporated reverse-blocking scheme to

prevent excessive leakage from the input terminals

in the event that the output voltage is greater than

the input voltage.

The input voltage is prioritized in the following

order: VCC50, VSB50, AUX33.
