1. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended

periods, may reduce device reliability.

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.
