AP1120 series are low dropout positive regulator to provide 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 3.3V/2.5V or 3.3V/1.8V logic supply. AP1120 series are guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to 18V input supply.


  • 1.3V maximum dropout at full load current
  • Fast transient response
  • Output current limiting for each channel
  • Built-in thermal shutdown each channel
  • Good noise rejection
  • Dual output ch1=3.3V, ch2=2.5V (1.8V for B version)
  • Lead Free Package: SO-8
  • Lead Free Finish/ RoHS Compliant


  • PC Peripheral
  • Communication
