Data Sheet
3A LOW DROPOUT LINEAR REGULATOR
General Description
Features
AZ1085
The AZ1085 is a series of low dropout positive voltage
regulators with a maximum dropout of 1.5V at 3A of
load current.
The series features on-chip thermal shutdown. It also
includes a bandgap reference and a current limiting cir-
cuit.
The AZ1085 is available in 1.5V, 1.8V, 2.5V, 3.3V,
5.0V and adjustable versions. The fixed versions inte-
grate the adjust resistors. The adjustable version can
set the output voltage with two external resistors.
The AZ1085 series is available in standard packages of
TO-263-2, TO-263-3, TO-220-3, TO-252-2 (1), TO-
252-2 (2), TO-252-2 (3) and TO-252-2 (4).
