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 TO–3 package and at the junction of the wide and narrow portion of the output lead for the TO–218 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.
