= 6A. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
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.
These parameters, although guaranteed, are not tested in production.
