Rashi Gupta

Part Number: LM2576

Hi,

I am component Engineer working with Honeywell Aerospace.

While evaluating HPN 26010117-101 (having TI MPN ‘LM2576T-ADJ/S5001479’) we found that it is the screened part. TI MPN ‘LM2576T-ADJ’ is std option available on website.

Can you please help us in explaining the differences between the LM2576T-ADJ/S5001479 Vs LM2576T-ADJ.

Note:

Screening for -101 shall consists of , as a mimum, 100% processing of an electrical test at -40degC.

Hello,

I'm unable to find any reference to the part number LM2576T-ADJ/S5001479.

Do you have the device top mark or lot information?
