1A Low Dropout Voltage Regulators-Image

APE1117A is a low dropout positive adjustable linear regulator with a minimum of 1A output current capability. The regulator is able to operate with output capacitors as small as 1uF for stability. This product is specifically designed to provide well-regulated supply for low voltage IC applications, such as high-speed bus termination and low current 3.3V logic supply. APE1117A is also well suited for other applications, such as VGA cards. APE1117A is guaranteed to have lower than 1.4V dropout at full load current, making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4 to 12V of input supply.


  • 1.4V maximum dropout at full load current

  • Output current limiting
  • Built-in thermal shutdown
  • Needs only 1uF capacitor for stability
  • Good noise rejection
  • 3-Terminal, Adjustable
  • Low ESR ceramic capacitor for output stability
  • RoHS-compliant
