LP3874-NDC topside marking.

Other Parts Discussed in Thread: LP3874

Good day, ladies and gentlemens.

 Where I can find topside marking description info (year, month, etc.) for NDC package (SOT223-5, f.e. for LP3874EMP-x.x) ?

Nor "ABC Marking Formats" (http://www.ti.com/general/docs/topsidemarkingformats.tsp?actionPerformed=listPkgTopSideFormats&pkg=ABC thru. "NDC") nor "Part Marking Look Up"  (http://www.ti.com/general/docs/partmarking/partmarkinghome.jsp thru. LHFB) can't help me. Also native NSC site (http://www.national.com/en/quality/marking_conventions.html) already unaccessible.

 Thank you for advise.

With best wishes (73), Stanislaw Leschinsky.

    This is more of a generic question for the web page team, not so much specifically for the LP3874 LDO only.

    I looked, and I also can't find any info where you would expected it to be.

    I do know that this month (Nov 2012) the SVA (formerly National Semiconductor) databases for ordering information are being assimilated into the TI databases, so this loss of detail information just might be a temporary situation.

    No idea if the SVA top-mark for lot tracability will be changed to match the existing TI format, or not.

    From what I can tell from the historical/archived (National Semi) top marking set-up, there are 2 lines for LP3874EMP-x.x top-side mark:

       Line 1:   >2>X    = where '>2' is a two digit date code, and '>X' is a two character die run trace code

       Line 2 :   LHEB   = LP3874EMP-1.8

    See tables 4, 5, and 6 ...
