General Description
Features
Data Sheet
AZ1084
The AZ1084 is a series of low dropout positive voltage · Low Dropout Voltage: 1.3V Typical at 5A
regulators with a maximum dropout of 1.5V at 5A of · Current Limiting and Thermal Protection
load current.
· Output Current: 5A
The series features on-chip thermal limiting which pro- · Current Limit: 6.5A
vides protection against any combination of overload · Operating Junction Temperature Range: 0 to
and ambient temperatures that would create excessive
125oC
junction temperatures. It also includes a trimmed band- · Line Regulation (Adj Version): 0.015% (Typical)
gap reference and a current limiting circuit.
· Load Regulation (Adj Version): 0.1% (Typical)
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.
The AZ1084 series is available in standard packages of
TO-263-3, TO-263-2, TO-220-3, TO-252-2 (1), TO-
252-2 (2), TO-252-2 (3) and TO-252-2 (4).
