General Description
Features
Data Sheet
AZ1084
The AZ1084 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 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 AZ1084 is available in 1.5V, 1.8V, 2.5V, 2.85V,
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 AZ1084 series is available in standard packages of
TO-263-2, TO-263-3, TO-220 and TO-252.
