NOT RECOMMENDED FOR NEW DESIGN
USE AZ1117C/E
1A DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR
Description
AP1117 is a low dropout positive adjustable or fixed-mode regulator
with 1A output current capability. The product is voltage specifically
designed to provide well-regulated supply for low 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 18V input supply. AP1117 is available both in commercial
temperature grade (AP1117) and in industrial temperature range
(AP1117I) (SOT223).
