Is there a proper way to heat sink an adjustable voltage regulator?
I used a screw and nut and a little bit of thermal paste to affix the sink but beyond that I don't know if there anything I can do better (or even if it needs anything better)

thanks

It sounds good.

Do you have the right size of heatsink?

 

If you are not having any thermal issues at this point, then you don't need to do anything else.

If you need more heat sink capability, you can always use a larger heat sink or a fan to cool the part down.

 

I'm using a to-220.

 

That's fine. Unless you are having a problem then there is no problem. What you have already done sounds good.

Check the temperature of the part in its final enclosure with a maximum load if you are worried.

 

Hello,

Here is a link from ESP on heatsinks:

just make sure the heat sink is not connected to GND or metal casing directly
if that is the case use mica and isolation washers
