unregulated supply to BS1usb?

After having much fun with my standard BS1, I eventually fried it with a misplaced I/O connection. Tried to replace the regulator but it seems the damage is far more extensive.
Time for an upgrade, so I ordered the new BS1usb to avoid using serial adapters. This week I received the cute little circuit, but got confused about how to connect it to an unregulated power supply, as I used to do with my old friend (RIP) when operating stand alone, disconnected from the PC.
Sure I can use an external regulator to Vdd and Vss, but wondered if there is some way to take advantage of the embedded regulator, assuming there is one, of course. I found no information about this neither here in the forum nor in the BS1usb-v1.1.pdf document.
I would appreciate any comments by the experienced people. Thanks in advance,
Paulo
