Note 1. Although power dissipation is internally limited, these specifications are applicable for power

dissipations of 20W.

Note 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.
