Re: Thandar TG2001
It shouldn't be possible for an LM317 etc, to get hot if just that faulty, as the only high-current path is from input to output - As it's an adjustable regulator, there isn't a ground pin, but an adjust pin connected via a resistor potential-divider to it's output.
So for it to get hot, there must be a fault elsewhere, like a short on it's output.
Note: The metal tab on the TO-220 LM317T is the Output connection, so must be electrically insulated from any heatsink that is grounded.
