General Description
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.
Applications
• PC peripheral
• Communication
