General Description

The H1085E is a 3A low-dropout positive voltage regulator. It is available in fixed and adjustable output voltage

versions. Over Current and thermal protection are integrated onto the chip. Output current will decrease while it

reaches the pre-set current or temperature limit. The dropout voltage is specified at 1.2V Maximum at full rated

output current. H1085E Series provides excellent regulation over variations due to changes in line, load and

temperature. H1085E is three terminal regulator and available in popular packages.
