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 package. 2) Test Conditions unless othewise stated: VIN – VOUT = 5V , TJ = 25°C , IOUT = 2.5A. Although power dissipation is internally limited, these specifications apply for dissipations of 50W and IMAX = 5A. Semelab plc. Telephone +44(0)1455 556565. Fax +44(0)1455 552612.
