AP1184 is a 4A 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 the switch can be achieved without the cost and complexity associated with switching regulator. One such application is the new graphic chipsets that requires anywhere from 2.4V to 2.7V supply.


  • 0.85V maximum dropout voltage at 4A load current
  • Built-in Thermal shutdown
  • Output current limiting
  • Adjustable or fixed output voltage1.5V, 1.8V, 2.5V, 3.3V, 5.0V
  • Fast transient response
  • Good noise rejection
  • Packages: TO220-5L and TO263-5L
  • Lead Free Finish/ RoHS Complian
