Linear Integrated Systems, Inc. LS31 marking

There was some confusion regarding parts manufactured by Linear Integrated Systems, Inc. marked with “LS31.” This marking is used on multiple devices, including the LS310, LS311, LS312, and LS313. During manufacturing, each device marked LS31 is individually hand-measured and then sorted into the appropriate bin corresponding to its specific ordering part number. I have attached part marking information for reference.
