Where can I find a document that details how the STBB1-A components are marked?

I looked through the datasheet looking for a section that details what markings I can expect to see on an STBB1-A regulator IC, but I couldn't find anything. I imagine it will just be an abbreviation and a date code and/or factory location, but I'd like to know for certain. Perhaps it is in a separate document??

    The Y stands for the fab and the following number for year and ww, e.g. 2018, week 12.

    Welcome, @PDuda.1​, to the community!

    Unfortunately, no official document is available for marking.

    The devices are marked:

    BB1

    A

    The packaging bag is marked:

    BB1 A

    Does it answer your question?

    Regards

    Ok, thanks! That does answer my original question.

    But as a follow up, could you provide any details regarding the top line marking? I see some as "Y810" and others "Y812".
