3A LOW DROPOUT LINEAR REGULATOR
Description
The AZ1085C 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 circuit.
The AZ1085C is available in 1.5V, 1.8V, 2.5V, 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 AZ1085C series is available in standard packages of TO263,
TO263-2, TO252-2 (3), TO252-2 (4) and TO252-2 (5).
