These specifications are applicable for power dissipations up to 30W for the TO-3 (NDS) package and 25W for the TO-220 (NDE)

package. Power dissipation is ensured at these values up to 15V input-output differential. Above 15V differential, power dissipation will

be limited by internal protection circuitry. All limits (i.e., the numbers in the Min. and Max. columns) are ensured to AOQL (Average

Outgoing Quality Level).

(2)

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

heating effects are covered under the specifications for thermal regulation.
