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 package and on the back of the heat tab for the TO–218, TO–220 and TO–257 packages.

2) Test Conditions unless othewise stated: VIN – VOUT = 5V , TJ = 25°C , IOUT = 1.5A.

Although power dissipation is internally limited, these specifications apply for dissipations of 30W for the TO–3, TO–218 and

TO–257 packages, and 25W for the TO–220 package; IMAX = 3A.
