Pragmatically "safe" current sourced from Vcc on Digispark?

[robmack]

As I read the schematic, the MC78M05BD regulator on the Digispark can provide regulated +5V on Vcc if Vin is used to power the board.  First question, is this correct?  This feature is explicitly called out on the Digispark Pro Pin Out Diagram but nothing is mentioned for the Digispark.

The spec sheet for the MC78M05BD states that the maximum current this regulator is capable of sourcing is 500mA with adequate heatsinking.  I don't believe the design of the Digispark board provides adequate heatsinking, so I guess that the maximum current is less than 500mA.  Second question, what is the practical limit for current that Vcc can source with this design?

VIN pin takes 7-12v (6-32 may work but over 12 will probably need some heat sinking) and can output 500ma (but over 100-200 might need some heat sinking)

Thanks.  That certainly didn't pop out of the page.  It might help to have a section of the wiki for electrical design topics and one for software design topics rather than mixing them on the same page.
