AAT1202
250-mA MULTI-INPUT LOW-DROPOUT REGULATOR
WITH DUAL -OUTPUT POWER MANAGEMENT
Features
Description
z Complete Power Management
The AAT1202 is a multi-input low-dropout
z Automatic Input Voltage Selection
regulator that provides dual constant output supply
3.3V & 1.8V at the output capable of driving a
z Input Voltage Source Detector With
250-mA load.
Hysteresis
The output (OUT18) can be disable by connect
z 250-mA Load Current Capability With
VCC50 or VSB50 or AUX33 Input Source
z Integrated Low rDS (on) Switch
EN18 pin to GND.
The AAT1202 provides dual regulated power
output for systems that have multiple input
sources and require dual constant voltage source
z Dual Regulated Output 3.3V (fixed) & 1.8V
(fixed)
z Output Short Circuit Protection
with a low-dropout voltage. This is a 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.www.DataSheet4U.com
Pin Configuration
Transitions may occur from one input supply to
another without generating a glitch outside of the
specification range on the 3.3-V & 1.8-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.
