Re: Raduino transistor getting hot

That is a linear voltage regulator (7805).

How hot is hot? Can you keep your finger on it?

The temperature increases with the voltage applied. I use mine at 13.8V power source voltage and is warm, not hot. I can take a measurement of the temperature after 30 minutes and let you know how my regulator is doing.

Good luck,
