AP1122 is a low dropout positive fixed-mode regulator with 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 1.2V logic supply.

AP1122 is also well suited for other applications such as VGA

cards. AP1122 is guaranteed to have lower than 1.3V dropout at

full load current making it ideal to provide well-regulated outputs

of 1.2 output voltage with 2.5V input voltage supply.
