DESCRIPTION

The IRU1120 is an adjustable linear voltage regulator. It is packaged in a 5-pin ultra thin-pak surface mount package. The adjustable output voltage can be set from 1.25V and up using a simple resistor divider. The input power can be supplied by a single 5V supply. The regulator is capable of supplying 2 Amps of continuous current with an input voltage of 5V. The output is protected by both current limit and thermal shutdown circuits.
