@CentralFan1976 posted:I’d check to see if it’s tab is soldered to the board, and if it is, see if they’re using thermal vias to get the heat to the bottom of the PCB. If it’s not soldered, then I’d try bending the legs up and get it to stand and then you could attach a larger heat sink to it.
It's clearly soldered to the board, it's a D-PAK surface mount part. The only connection to the center pin is the pad.
