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 θ th,TAB-A, to improve overall thermal resistance (θ th,J-A).
