I've accidentally tried it with 7805s shorting the output to ground, they get hot as hell with no heatsink but they don't blow up and work fine afterwards.
Looking at the video you've got it wired up backwards, so it's no surprise it didn't work properly, check the datasheet.
I did it on purpose anyway , I knew it wouldn't work as intended , this chip has been faulty from day 1 .
But the main purpose was to make it smoke
Simply speaking , i sent 2A through the input and ground . and grounded it from the output .
That would be directly sending that amount of power through the input and to ground and then letting it leave from the output , therefore it will try to regulate and end up turning into a heater .
I should have allowed it to try powering up my MASSIVE
alpine amp .
It's amazing how long it lasted . 1 hour of 2A going through it .
