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) |

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. ;-) |

3DMovieList, can you measure the height/width/length of the package? |

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. |
