Notes :
1. Although power dissipation is internally limited, these specifications are applicable for power dissipation of :
2W for TO-39
15W for TO-220
20W for TO-3 Package
I
O(max)
is :
1.5A for TO-3 and TO-220
0.5A for TO-39
2. Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in out-
put voltage due to heating effects are covered under the specification for thermal regulation.
