AAT3221 - 150 mA Nanopower LDO Linear Regulator

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.
