Changes in output voltage due to heating effects are covered under thermal regulation specifications. Load regulation is measured at a point 1/8" 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 SMD1package, and 1/8" below the base of the package on the output pin of the TO-257 package. 2) Test Conditions unless otherwise stated: VIN - VOUT = 5V , IOUT = 0.1A , PMAX = 2W , IMAX = 0.5A VMAX = 40V for standard series , 50V for HV series.
