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
1
thermal regulation specifications. Load regulation is measured at a point / ” from the bottom of the package for the TO–3 and TO–66 packages, at the junction of the

wide and narrow portion of the output lead for the SMD packages, and / ” below the base of the package on the output pin of the TO–257 package.
