General Description
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.
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.
