Help with SMB BJT identification?

3-terminal (well 4, including the tab) SOT-89/TO-243 (4.5 x 2.5 mm) package.
Marked:
2108A
2216/36
Thanks.

Probably.
Maybe it's a MicrOne ME2108A - a switching regulator. PDFs may be available only with chinese (or the like) text...

P.S. Google for SOT89 2108A to get some results...

Thanks Tilmann. Found a useful datasheet:

The example for the 2108A in the datasheet duplicates the one in my circuit.
Cheers.
