1.

Although power dissipation is internally limited, these specifications are applicable for power dissipation of:

15 W for TO-220 and 20 W for TO-3 package; IO(max) is 1.5 A.

2.

Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output

voltage due to heating effects are covered under the specification for thermal regulation.
