General Description
AP1117 is a low dropout positive adjustable or
fixed-mode 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 logic supply.
AP1117 is also well suited for other applications
such as VGA cards. AP1117 is guaranteed to have
lower than 1.4V dropout at full load current making
it ideal to provide well-regulated outputs of 1.25 to
5.0 with 6.4V to 12V input supply.
