Hi.
I'm wondering if anybody can help me. I made a voltage regulator with LM338T
and everything works OK. The problem is in heatsink. In have to calc it and
I don't know how. Can somebody help me. Information from datasheet of LM338
are:
Rjc=4°C/W
Rja=50°C/W
Rcs=0,5°C/W
Ta=40°C
Pd=25W
Now can somebody give me the whole calc of heatsink.
THX to anybody.
