Description
The AAT1201 is a multi-input low-dropout
regulator (LDO) designed for LAN card. It
provides dual constant output supply 3.3V & 2.5V
at the output capable of driving a 250-mA load.
The output (OUT25) can be disabled by
connecting EN25 pin to GND.
The AAT1201 provides 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 LDO regulator for
either VCC50 or VSB50 inputs, and a
low-resistance bypass switch for the AUX33
input.
The AAT1201 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 & 2.5-V output. The device is
equipped with an incorporated reverse-blocking
scheme to prevent excess leakage from the input
terminals in the event when the output voltage is
greater than the input voltage.
The input voltage is prioritized in the following
order: VCC50, VSB50, AUX33.
