General Description
The H1117J is a 1A low-dropout positive voltage regulator. It is available in fixed and adjustable output voltage
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. H1117J Series provides excellent regulation over variations due to changes in line, load and
temperature. H1117J is three terminal regulator and available in popular packages.
