AP1117

1A LOW DROPOUT POSITIVE ADJUSTABLE OR

FIXED-MODE REGULATOR

General Description

Features

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 in commercial temperature

grade.
