The AAT3232 Low Dropout Linear Regulator is
ideal for portable applications where longer
battery life is critical. It features low quiescent
current (30碌A(chǔ) 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鈥檚 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.
