NOTES:
1.Although power dissipation is internally limited, specifications apply only for PO
≤
Pmax, Pmax = 25 W.
2.Line and load regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately.
Pulse testing with low duty cycle is used.
