Notes:
1/ 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 specification for thermal regulation. With exception of cases U and 2, all output measurements are referenced
to the case. Measurements taken at the output lead must be adjusted for lead resistance.
2/ If not tested, shall be guaranteed to the specified limits.
