Devices marking

[Manman]

Hello,

I have some doubt on part number L9942XP1TR. What the meaning for letter "RR" on top mark. Can you provide some parts mark information?

Thanks

Man

Hi Billy, can we get some actual definitive answer here, so the questions don't need to be answered twice or for multiple people. Is the "RR" something ST put here? Was it for a specific customer or variant?
