„ General Description
AP1116 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 0.5A 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.
AP1116 is also well suited for other applications
such as VGA cards. AP1116 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated outputs of 1.25V to 5V with
up to 18V input supply.
