AAT3221/2

150mA NanoPower™ LDO Linear Regulator

™

PowerLinear

General Description

Features

The AAT3221 and AAT3222 PowerLinear

NanoPower low dropout (LDO) linear regulators

are ideal for portable applications where extended

battery life is critical. These devices feature

extremely low quiescent current, typically 1.1µA.

Dropout voltage is also very low, typically less than

200mV at the maximum output current of 150mA.

The AAT3221/2 have an enable pin feature which,

when asserted, will enter the LDO regulator into

shutdown mode, removing power from its load and

offering extended power conservation capabilities

for portable battery-powered applications.

5-Pin SOT23 or 8-Pin SC70JW Package

-40°C to +85°C Temperature Range

The AAT3221/2 have output short-circuit and over-

current protection. In addition, the devices also

have an over-temperature protection circuit, which

will shut down the LDO regulator during extended

over-current events. The devices are available

with active high or active low enable input.

The AAT3221 and AAT3222 are available in Pb-free,

space-saving 5-pin SOT23 packages. The AAT3221

is also available in a Pb-free, 8-pin SC70JW pack-

age. The device is rated over the -40°C to +85°C

temperature range. Since only a small, 1µF ceram-

ic output capacitor is recommended, often the only

space used is that occupied by the AAT3221/2 itself.

The AAT3221/2 provide a compact and cost-effec-

tive voltage conversion solution.

Applications

•

Cellular Phones

Digital Cameras

Handheld Electronics

Notebook Computers

PDAs

Portable Communication Devices

Remote Controls

The AAT3221 and AAT3122 are similar to the

AAT3220, with the exception that they offer further

power savings with an enable pin.
