APPLICATIONS
The IRU1120 is an adjustable linear voltage regulator. It
is packaged in a 5-pin ultra thin-pak surface mount pack-
age. 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.
