AAT3201
AAT3201
150mA OmniPower™ LDO Linear Regulator
General Description
The AAT3201 PowerLinear™ OmniPower Low
Dropout Linear Regulator is ideal for systems
where a low cost solution is critical. This device
features extremely low quiescent current which is
typically 20µA. Dropout voltage is also very low,
typically 200mV. The AAT3201 has an Enable pin
feature, which when pulled low will enter the LDO
regulator into a shutdown mode removing power
from its load and offering extended power conser-
vation capabilities for portable battery powered
applications.
The AAT3201 has output short circuit and over cur-
rent protection. In addition, the device also has an
over temperature protection circuit, which will shut-
down the LDO regulator during extended over-cur-
rent events.
The AAT3201 is available in the space saving 5-pin
SOT23 package. The device is rated over a -40°C
to 85°C temperature range. Since only a small, 1µF
ceramic output capacitor is recommended, the
AAT3201 is a truly cost effective voltage conversion
solution.
The AAT3201 is similar to the AAT3200 with the
exception that it offers further power savings with
its enable pin.

Function
Input pin
Ground connection pin
Enable pin - When pulled low the PMOS pass transistor turns off and all
internal circuitry enters low-power mode, consuming less than 1µA.
Not Connected
Output pin - should be decoupled with 1µF or greater capacitor
