Diodes Incorporated
5A LOW DROPOUT LINEAR REGULATOR
Description
The AZ1084C 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 provides protection
against any combination of overload and ambient temperatures that
would create excessive junction temperatures. It also includes a
trimmed bandgap reference and a current limiting circuit.
The AZ1084C 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 AZ1084C series is available in standard packages of TO263,
TO263-2, TO252-2 (3), TO252-2 (4) and TO252-2 (5).
