3A LOW DROPOUT LINEAR REGULATOR
Description
The AZ2085 series is low dropout positive voltage regulators with a
maximum dropout of 1.5V at 3A of load current.
The device features on-chip thermal shutdown. It also includes a
bandgap reference and a current limiting circuit.
The AZ2085 is available in adjustable version. The adjustable version
can set the output voltage with two external resistors.
The AZ2085 series is available in standard packages of TO252-2 (3)
and TO252-2 (5).
