The APL1084 is a low dropout three-terminal adjustable
regulator with 5A output current capability. In order to
obtain lower dropout voltage and speed up transient
response, which is critical for low voltage applications,
the APL1084 has been optimized. The output available
voltage range of adjustable version is from 1.25 to 5.75V
with an input supply below 7V, and the fixed 3.3V output
voltage device is also available. Current limit is trimmed
to ensure specified output current and controlled short-
circuit current. On-chip thermal limiting provides protec-
tion against any combination of overload that would cre-
ate excessive junction temperatures. The APL1084 is
available in both the through-hole and surface mount
versions of the industry standard 3-pin TO-220,TO-252,
and TO-263 power packages.

Ordering and Marking Information
Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note 2: See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulations are
measured at a constant junction temperature by low duty cycle pulse testing.
Note 3 :The value could be varied when heat sink size is different. Use larger heat sink or larger PCB size, which improves
θth,TAB-A, to improve overall thermal resistance (θth,J-A).
