„ General Description
AP1121 series are low dropout positive regulator
with minimum of 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 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.
