I put a couple TO220 linear regulators on a small piece of vector board that plugs into JP105.? The 3.3v TO220 regulator got too hot to touch, so I bolted a copper plate to the tab.? ?Can't imagine how that dinky 78M33 manages to dissipate so much heat through one or two skinny Sot23 ground pins.

I'd love to use a bigger regulator, but there's almost no space there. Or
is there? Did you fit a bigger regulator?
