7(&+ 300mA CMOS Low Drop Out Linear Regulator
General Description
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.
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.

Function
Input voltage pin – should be decoupled with 1µF or greater capacitor.
Ground connection pin
Enable pin – pin is internally pulled high. When pulled low the PMOS pass transistor
turns off and the device enters low-power mode, consuming less than 1µA.
Bypass capacitor connection -- to improve AC ripple rejection, connect a 1nF
capacitor to GND. This will also provide a soft start function.
Output pin – should be decoupled with 2.2µF or greater output capacitor. See
Detailed Description section for further information.
