AAT3236
300mA CMOS High Performance LDO
General Description
Features
PowerLinear™
The AAT3236 is a MicroPower™ Low Dropout
Linear Regulator designed to deliver a continuous
300mA output load current and is capable of han-
dling short duration current peaks up to 500mA.
With a very small footprint SOT23-5 package it is
ideally suited for portable applications where low
noise, high power supply ripple rejection, extended
battery life and small size are critical. The AAT3236
features fast transient response and low output self
noise for powering sensitive RF circuitry. Other fea-
tures include low quiescent current, typically
100µA, and low dropout voltage, typically 300mV at
full output load current. The device has internal out-
put short circuit protection and thermal shutdown to
prevent damage under extreme conditions.
The AAT3236 also features a low-power shutdown
mode for longer battery life. A bypass pin is pro-
vided to improve PSRR performance by connect-
ing an external capacitor from the AAT3236's refer-
ence output to ground.
The AAT3236 is available in a space saving
SOT23-5 or SC70JW-8 package in 7 factory pro-
grammed voltages of 2.5V, 2.7V, 2.8V, 2.85V, 3.0V,
3.3V, or 3.5V.
