Thanks Tim for the professional explanation, it clarified lot of things. Well, this is a video that show my setup and heatsink boiling a water drop: Or reduce V inthis device has a low dropout so you can reliably use anything from 9V on up. I did some power regulator using the LMCT. I took a few shortcuts in the above equations. Doesn’t that configuration works as a “1A current generator”? Hello Grumpy, Thanks for the link. There are cloned, pirated cheap and bad components in the market?

Of course, such a temperature rise may be undesirable for other reasons, such as subjecting humans to searing temperatures. What is important here is how much power is dissipated by the voltage regulator: For a discussion of power issues see: As example I have some LM that gets hot and other, from another manufacturers that doesn’t in same conditions, so it makes me think about it. Let’s say you go with 12V power supply: 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.

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. What is important here is how much power is dissipated by the voltage regulator: It’s working to regulate voltages but it’s getting really very hot.

The conditions for the test was: I used some generous heat sink but when working it can easily boil water drops. It’s working to regulate voltages but it’s getting really very hot. I did some power regulator using the LMCT. LMCT gets very hot. Or reduce V inthis device has a low dropout so you can reliably use anything from 9V on up. Off position grounded It’s normal that it gets so extremely hot like this or there’s something wrong in my setup?

The conditions for the test was: The datasneet also has thermal regulation built in, it will turn itself off before it burns up. Let’s say you go with 12V power supply: LMCT gets very hot.
