Note:
1. Although power dissipation is internally limited, specifications apply only for PO ≤ Pmax, Pmax = 25W
2. Load and line regulation are specified at constant junction temperature. Change in Vo due heating effects must be taken into
account separately. Pulse testing with low duty is used. ( PMAX = 25W)
