AAT3232
300mA CMOS Low Drop Out Linear Regulator
7(&+
General Description
Features
The AAT3232 Low Dropout Linear Regulator is
ideal for portable applications where longer
battery life is critical. It features low quiescent
current (30µA typical) and low dropout voltage
(300mV max) at full output current. The device is
able to protect itself from short circuit conditions
with fold back current limiting. Thermal shutdown
is activated to prevent damage under extreme
conditions.

Low Dropout - 300mV (max) at 300mA
Guaranteed 300mA Output
High accuracy
30µA Quiescent Current
Current limit protection
Short circuit current fold back
Over-Temperature protection
Noise reduction bypass capacitor
Shutdown mode for longer battery life
Low Temperature coefficient
7 Factory programmed output voltages
SOT-23 5-pin package
The AAT3232 also features
a
low-power
shutdown mode for longer battery life. A pin is
provided to improve PSRR performance, by
connecting an external capacitor from the
AAT3232’s reference output to ground.
The AAT3232 is available in a space saving 5-pin
SOT-23 in 7 factory programmed voltages of
2.5V, 2.7V, 2.8V, 3.0V, 3.3V, 3.5V and 3.8V.
