Data Sheet

5A LOW DROPOUT LINEAR REGULATOR

General Description

The AZ1084 is a series of low dropout positive voltage

regulators with a maximum dropout of 1.5V at 5A of

load current.

The series features on-chip thermal limiting which pro-

vides protection against any combination of overload

and ambient temperatures that would create excessive

junction temperatures. It also includes a trimmed band-

gap reference and a current limiting circuit.

The AZ1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and

5.0V versions. The fixed versions integrate the adjust

resistors. It is also available in an adjustable version

which can set the output voltage with two external

resistors.

The AZ1084 series is available in standard packages of

TO-263-3, TO-263-2, TO-220-3, TO-252-2 (1), TO-

252-2 (2), TO-252-2 (3) and TO-252-2 (4).
