General Description
The H1117E is a 1A low-dropout positive voltag e regulator. It is available in fixed and adjustable output v oltage
versions. Over curre nt and thermal protection are integr ated onto the chip. Output current will decr ease while it
reaches the pre-set current or tem perature limit. The dropout voltage is specified at 1.2V Maximum at full rated
output current. H1117E Series provides excellent regulation over variations due to changes in line, load and
temperature. H1117E is three terminal regulator and available in popular packages.
