AAT1203
250-mA MULTI-INPUT LOW-DROPOUT REGULATOR
WITH VAUX SWITCH
Features
z Complete Power Management
Description
The AAT1203 is a multi-input low-dropout
z Automatic Input Voltage Selection
regulator designed for LAN cards. It provides
z Input Voltage Source Detector With
Hysteresis
constant output supply 3.3V at an output capable
of driving a 250-mA load.
z 250-mA Load Current Capability With
VCC50 or VSB50 or AUX33 Input Source
z Integrated Low rDS(on) Switch
The AAT1203 is equipped with regulated power
output for systems that have multiple input
sources and require constant voltage source with a
z Regulated Output 3.3V (fixed)
z Output Short Circuit Protection
low-dropout voltage. This is an intelligent power
source selection device with a low-dropout
regulatorwww.DataSheet4U.com for either VCC50 or VSB50 inputs, and
Pin Configuration
a low-resistance bypass switch for the AUX33
input.
The AAT1203 allows transitions to progress
smoothly from one input supply to another
without generating a glitch outside of the specified
range of the 3.3-V output. The device has an
incorporated reverse-blocking scheme to prevent
excess 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.
