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 and TO–66 pack-
ages, at the junction of the wide and narrow portion of the output lead for the TO–220 package, and 1/8” below the base of the package on the out-
put pin of the TO–257 package.
2) Test Conditions unless othewise stated:
VIN – VOUT = 5V , TJ = 25°C , IOUT = 0.5A , PMAX = 20W , IMAX = 1.5A
VMAX = 40V for standard series , 60V for HV series.
