AP1121 is a low dropout positive regulator which provides 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 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.
