AP1117/AP1117I
1A DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR
Description
Pin Assignments
AP1117 is a low dropout positive adjustable or fixed-mode regulator
SOT89-3
with 1A output current capability. The product is voltage specifically
designed to provide well-regulated supply for low IC applications such
( Top View )
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
