E-mail: sales@semelab.co.uk Website: http://www.semelab.co.uk Semelab Plc reserves the right to change test conditions, parameter limits and package dimensions without notice. Information furnished by Semelab is believed to be both accurate and reliable at the time of going to press. However Semelab assumes no responsibility for any errors or omissions discovered in its use. Semelab encourages customers to verify that datasheets are current before placing orders. 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 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 SMD packages, 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 = 0.5A , PMAX = 20W , IMAX = 1.5A, VMAX = 40V for standard series , 50V for HV series.
