3-terminal (well 4, including the tab) SOT-89/TO-243 (4.5 x 2.5 mm) package.

Marked:
2108A
2216/36

Thanks.

Well, “BJT” may be a misnomer. Don’t know what it is...

Probably.

Maybe it's a MicrOne ME2108A - a switching regulator.

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.
