How must one read the datasheet to calculate what heatsink to use?
For example, say i'm using a LM7805
https://www.electro-tech-online.com/custompdfs/2005/04/LM7512CPDF.pdf
And i'm inputting 17V and using a current of 0.5A
That would make 17 - 5 = 12V * 0.5A = 6W of dissipation.
Now, what factors and graphs in the datasheet should i use and how to see what kind of heatsink to use.
