AZ1084
OBSOLETE – PART DISCONTINUED
5A LOW DROPOUT LINEAR REGULATOR
Description
Features
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 provides 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, 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.
