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 at a point

" from the bottom of
the package for the TO3 and TO66 packages, at the junction of the wide and narrow portion of the output lead for the
SMD1package, and
