Fake part.
National Semiconductor logo with a 1708 date code -- 8th week of 2017.
First -- the part marking should not be coming off like that on a 2 year old part.
Second -- National Semiconductor was bought out by Texas Instruments in 2011... six years before this part was supposedly made by National Semi.
I think a lot of the fakes out there are old LM309K's which were the same thing but 1 amp. These were cheaper and more plentiful for quite awhile.
