General Description

APE1117 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.

APE1117 is also well suited for other applications

such as VGA cards. APE1117 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.
