Jan. 2013 Rev. 2. 5 BCD Semiconductor Manufacturing Limited
General Description
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, 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).

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under"Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum
Ratings" for extended periods may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical
specifications do not apply when operating the device outside of its operating ratings. The maximum allowable
power dissipation is a function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal
resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient tem-
perature is calculated using: PD(max)=(TJ(max) -TA)/θJA. Exceeding the maximum allowable power dissipation will
result in excessive die temperature, and the regulator will go into thermal shutdown.
