Description

AP1121 is a 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. AP1121 is a 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.

Feature(s)

  • 1.3V maximum dropout at full load current
  • Fast transient response
  • Output current limiting for each channel
  • Built-in thermal shutdown for each channel
  • Good noise rejection
  • Dual output ch1 = 3.3V, ch2 = 2.5V (ch2 = 1.8V for version B)
  • SO-8: Available in “Green” Molding Compound (No Br, Sb)
  • Lead Free Finish/ RoHS Compliant

Application(s)

  • PC peripheral
  • Communication
