AAT3236
300mA CMOS High Performance LDO
General Description
The AAT3236 is a MicroPower low dropout (LDO)
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 (PSRR),
extended battery life, and small size are critical.
The AAT3236 features fast transient response and
low output self noise for powering sensitive RF cir-
cuitry. Other features include low quiescent cur-
rent, typically 100µA, and low dropout voltage, typ-
ically 300mV at full output load current. The device
has internal output short-circuit protection and ther-
mal 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 device reference
output to ground.
The AAT3236 is available in a Pb-free, space-sav-
ing SOT23-5 or SC70JW-8 package in nine facto-
ry-programmed voltages: 2.5V, 2.7V, 2.8V, 2.85V,
3.0V, 3.1V, 3.3V, 3.5V, or 3.6V.
