The problem isn't that the regulator can't tolerate a short circuit, it can and often does (users frequently mis-wire the endstop switches). I think the problem is the transient created when short on the 3.3V rail is released. The shape and size of that transient depends on the wiring to the endstop switch. We're looking at adding transient suppressors on the newer boards.

If yes, check the 5A fuse, also inspect U3 (small square chip not far from the VIN connector) for signs of damage If no, check that the I_5V_EN jumper is in place
