AAT3221 - 150mA NanoPower LDO Linear Regulator

Download the AAT3221 datasheet PDF. This datasheet also covers the AAT variant, as both devices belong to the same 150ma nanopower ldo linear regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The AAT3221 and AAT3222 PowerLinear™ NanoPower Low Dropout Linear Regulators are ideal for portable applications where extended battery life is critical.

Key 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.
