Hi everybody,
I am trying to calculate the temp. of my MC7805 regulator after attaching it to Heat sink of type P/N 6073B according to POWER SUPPLY COOKBOOK page 17 ( attached), I found the first equation correct, but my calculator keeps telling me that the second equation = 197 not 84.4.
What's wrong with my calculation?
