voltageapplications, the APL1084 has been optimized. The output available voltage range of adjustable version is from 1.25~5.75V 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. Onchip thermal limiting provides protection against any combination of overload that would create 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 TO263 power packages.

NOTE 1: 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 2 :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).
