Unless otherwise specified, the following specifications apply over the operating ambient temperature 0°C
otherwise noted and the following test conditions:.
Note 2: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating
Note 3: These parameters, although guaranteed, are not tested in production.
