5A LOW DROPOUT LINEAR REGULATOR
General Description
Features
Data Sheet
AZ1084C
The AZ1084C is a series of low dropout positive volt-
age regulators with a maximum dropout of 1.5V at 5A
of load current.
The series features on-chip thermal limiting which pro-
vides protection against any combination of overload
and ambient temperatures that would create excessive
junction temperatures. It also includes a trimmed band-
gap 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 ver-
sion which can set the output voltage with two external
resistors.
The AZ1084C series is available in standard packages
of TO-263-3, TO-263-2, TO-252-2 (3) and TO-252-2
(4).
