AAT3221/2

150mA NanoPower™ LDO Linear Regulator

™

PowerLinear

General Description

Features

The AAT3221 and AAT3222 PowerLinear™

NanoPower Low Dropout Linear Regulators are

ideal for portable applications where extended bat-

tery life is critical. This device features extremely

low quiescent current which is typically 1.1µA.

Dropout voltage is also very low, typically less than

200mV at the maximum output current of 150mA.

The AAT3221/2 has an Enable pin feature, which

when asserted will enter the LDO regulator into a

shutdown mode removing power from its load and

offering extended power conservation capabilities

for portable battery powered applications.

The AAT3221/2 has output short circuit and over

current protection. In addition, the device also has

an over temperature protection circuit, which will

shutdown the LDO regulator during extended over-

current events. It is available with active high or

active low enable input.

Applications

The AAT3221 and AAT3222 are available in space

saving 5-pin SOT23 packages. The AAT3221 is

also available in the 8-pin SC70JW package. The

device is rated over a -40°C to 85°C temperature

range. Since only a small, 1µF ceramic output

capacitor is recommended, often the only space

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

AAT3221/2 is truly a compact and cost effective volt-

age conversion solution.

The AAT3221/2 is similar to the AAT3220 with the

exception that it offers further power savings with

its enable pin.
