Electrical Characteristics(MC78T15)
(V
Note:
1. Although power dissipation is internally limited, specifications apply only for P
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. ( P
