AP1122 - 1A LOW DROPOUT POSITIVE REGULATOR

General Description

AP1122 is a low dropout positive fixed-mode regulator with 1A output current capability.

The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 1.2V logic supply.

Key Features

  • 1.3V maximum dropout at full load current.
  • Fixed 1.2V± 2% output voltage.
  • Fast transient response.
  • Output current limiting.
  • Built-in thermal shutdown.
  • Good noise rejection.
  • Packages: SOT223-3L, TO252-3L, SOT89-3L, TO263-3L and TO220-3L.
  • SOT89-3L, SOT223-3L and TO252-3L: Available in “Green” Molding Compound (No Br, Sb).
  • Lead Free Finish/ RoHS Compliant (Note 1) (Top View) 3 VIN 2 VOUT 1 GND Tab is VOUT SOT2.

AP1122 1A LOW DROPOUT POSITIVE REGULATOR OBSOLETE – PART DISCONTINUED Description Pin Assignments AP1122 is a low dropout positive fixed-mode regulator with 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 1.2V logic supply. AP1122 is also well suited for other applications such as VGA cards. AP1122 is guaranteed to have lower than 1.3V dropout at full load current making it ideal to provide well-regulated outputs of 1.2 output voltage with 2.5V input voltage supply. Applications • PC peripheral • Communication Features • 1.3V maximum dropout at full load current • Fixed 1.
