Ok, my regulator passed away, so it is the high time to replace it..
I found (fortunately) an LF33 3.3V regulator in my junkbox, which has got the GND at its heat-sink fin
It fits perfectly on the BPill's bottom side, the LF33 heat-sink fin is soldered on the two pads (GND) of the Boot pins (from bottom side, of course). (Note: I removed the Boot pin headers in past).
The LF33 3.3V in that DPACK package is rated 500mA, so much better than the old one.

Below the picture.. Shorten and bend the LF33 pins a little bit such they are at least 1mm off the pcb.
