LMCT gets very hot. I did some power regulator using the LMCT. It’s working to regulate voltages but it’s getting really very hot.

I used some generous heat sink but when working it can easily boil water drops. Well, this is a video that show my setup and heatsink boiling a water drop: There are cloned, pirated cheap and bad components in the market?

As example I llm2941ct some LM that gets hot and other, from another manufacturers that doesn’t in same conditions, so it makes me think about it.

The conditions for the test was: Off position grounded It’s normal that it gets so extremely hot like this or there’s something wrong in my setup? What is important here is how much power is dissipated by the voltage regulator: The device also has thermal regulation built in, it will turn itself off before it burns up.

Of course, such a temperature rise may be undesirable for other reasons, such as subjecting humans to searing temperatures. Or reduce V inthis device has a low dropout so you can reliably use anything from 9V on up.

Let’s say you go with 12V power supply: I took a few shortcuts in the above equations. The heatsink equations ignore the thermal resistance between the package and the heatsink, but I figured there was more than enough math for everyone in there, but it illustrates the basic principles of calculating power dissipation and temperature rise.
