AZ1084
5A LOW DROPOUT LINEAR REGULATOR
Description Features
The AZ1084 is a series of low dropout positive voltage regulators with
Low Dropout Voltage: 1.3V Typical at 5A
a maximum dropout of 1.5V at 5A of load current.
Current Limiting and Thermal Protection
Output Current: 5A
The series features on-chip thermal limiting which provides protection
Current Limit: 6.5A
against any combination of overload and ambient temperatures that
Operating Junction Temperature Range: 0 to +125C
would create excessive junction temperatures. It also includes a
Line Regulation (Adj Version): 0.015% (Typical)
trimmed band-gap reference and a current limiting circuit.
Load Regulation (Adj Version): 0.1% (Typical)
Lead-Free Packages: TO263, TO-263-2, TO-220-3, TO-252-2 (3),
The AZ1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and 5.0V versions.
TO-252-2 (4), TO-252-2 (5)
The fixed versions integrate the adjust resistors. It is also available in
Totally Lead-Free; RoHS Compliant (Notes 1 & 2)
an adjustable version which can set the output voltage with two
external resistors.
Lead-Free Packages, Available in Green Molding Compound:
TO263, TO-263-2, TO-220-3, TO-252-2 (3), TO-252-2 (4), TO-
252-2 (5)
