Datasheet
H1084U Series
5A LOW DROPOUT POSITIVE VOLTAGE REGULATOR
Features
Applications
General Description
The H1084U is a 5A 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. H1084U Series provides excellent regulation over variations due to changes in line, load and
temperature. H1084U is three terminal regulator and available in popular packages.

... Thermal Consideration The H1084U series contain thermal limiting circuitry designed to protect itself for over-temperature conditions. Even for normal load conditions, maximum junction temperature ratings must not be exceeded. As mention in thermal protection section, we need to consider all sources of thermal resistance between junction and ambient. ...

... And with the input pin instantaneously shorted to ground. can damage occur. A crowbar circuit at the input of the H1084U can generate those kinds of currents, and a diode from output to input is recommended. Normal power supply cycling or even plugging and unplugging in the system will not generate currents large enough to do any damage ...
