1) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating effects are covered under thermal regulation specifications. Load regulation is measured from the bottom of the package for the TO3 package. 2) Test Conditions unless othewise stated: VIN VOUT = 5V , TJ = 25°C , IOUT = 2.5A. Although power dissipation is internally limited, these specifications apply for dissipations of 50W and IMAX = 5A.

1) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating effects are covered under thermal regulation specifications. Load regulation is measured from the bottom of the package for the TO3 package and at the junction of the wide and narrow portion of the output lead for the TO218 package. 2) Test Conditions unless othewise stated: VIN VOUT = 5V , TJ = 25°C , IOUT = 2.5A. Although power dissipation is internally limited, these specifications apply for dissipations of 50W and IMAX = 5A.
