AP1117/AP1117I
1A DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR
Description
AP1117 is a low dropout positive adjus table or fixed-mode re gulator
with 1A output c urrent capabilit y. The product is voltage specifi cally
designed to provide well-regulated supply for low IC applications such
as high-speed b us termination a nd low cur rent 3.3V logic supply.
AP1117 is also well suited for ot her applications such as VGA ca rds.
AP1117 is guar anteed to h ave lower tha n 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 18V input supply. AP1117 is available both in commercial
temperature gra de (AP1117) a nd in industrial temperature r ange
(AP1117I) (TO252 and SOT223).
