Data Sheet

3A LOW DROPOUT LINEAR REGULATOR

General Description

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, 2.85V,

3.3V, 5.0V and adjustable versions. The fixed versions

integrate 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-263-2L, TO-263-3L, TO-220 and TO-252.
