AP1186 is a 1.5A regulator with extremely low dropout voltage. This product is specifically designed to provide well-regulated supply for applications equiring 2.8V or lower voltages from 3.3V ATX power supplies where high efficiency of a switcher can be achieved without the cost and complexity associated with a switching regulator. One such application is the new graphic chip sets that require anywhere from 2.4V to 2.7V supply.


  • Adjustable or Fixed output voltage 1.5V, 1.8V, 2.5V, 3.3V, 5.0V
  • 0.5V Maximum Dropout voltage at 1.5A Load current
  • Built-in Thermal Shutdown
  • Output Current Limiting
  • Fast transient response
  • Good noise rejection
  • Packages: TO220-5L, TO263-5L
  • Lead Free Finish/RoHS Compliant for Lead Free products
