AAT3222 - 150 mA Nanopower LDO Linear Regulator

Download the AAT3222 datasheet PDF. This datasheet also covers the AAT3221 variant, as both devices belong to the same 150 ma nanopower ldo linear regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The AAT3221 and AAT3222 NanoPower™ Low Drop Out (LDO) linear regulators are ideal for portable applications where extended battery life is critical.

These devices feature extremely low quiescent current, typically 1.1 µA.

Key Features

  • Quiescent current: 1.1 µA.
  • Low dropout: 200 mV (typical).
  • Guaranteed output: 150 mA.
  • High accuracy: ±2%.
  • Current limit protection.
  • Over-temperature protection.
  • Extremely low power shutdown mode.
  • Low temperature coefficient.
  • Factory-programmed output voltages: 1.5 V to 3.5 V.
  • Stable operation with virtually any output capacitor type.
  • Active high or low enable pin.
  • Small, 5-pin SOT23 or 8-p.
