sinewave:
I do agree with it more than likely being not an LDO, due to the lack of caps around, figuring out the actual package would help as there are 4 or so footprints with a similar layout (2 pins on one side and 3 on the other)
3DMovieList:
A few folks have mentioned the Twitter thread.  For those following this discussion, the Twitter thread is here: https://twitter.com/3DMovieList/status/1583982843344326656?s=20&t=qZjoL39L_oq3PdYxA8_C-w
BUT let's keep the detailed discussion here.  ;-)
sinewave:
3DMovieList, can you measure the height/width/length of the package?
3DMovieList:
I don't have my notes with me at the moment, but when I originally tested the "good" J516T, it looked more like a diode package with several 0.6V diode drops identified using the multimeter.  But I didn't test thoroughly, and it was in-circuit, so at the time, I was just noticing a difference between the "good" and the "bad".
Hopefully I'll have time today to desolder a good J516T chip to allow some more detailed testing to check what the chip might be.
Thanks for all the good suggestions everyone.

I overlaid a SOT23-5 package on it visually and it matched.
