I'm currently working on my first circuit that dissipates enough power that I need to use a heatsink. The component in question is a TS1085CZ33 which I'm running with a maximum load of 2.8A dissipating around 7.5W. I'm just wondering a couple of things:
- Is the heatsink tab on these chips (I'm using the TO-220 variant) electrically connected internally? If so, what is it connected to?
- If it isn't connected should I ground the heatsink?
