LM4040: Average temperature coefficient of LM4040

Lacey Lin

Part Number: LM4040

Hi team,

My customer want to use the LM4040AxxI in -40degree to 105degree.

But they need to make sure maximum Average temperature coefficient is 100 ppm/C

For the LM4040Axxl, the recommendation temp is -40 to 85.

1. So can you help to provide when the temperature is up to 105 degree, what specs will be degrade and how worse.

2. What's the maximum Average temperature coefficient when the temperature is between the -40 and 105 degree?

Thanks a lot!

Lacey

    Hi Lacey,

    The LM4040AxxI as you noticed can only have guaranteed EC table specs between -40C and 85C. Therefore we do not have data for these devices greater than 85C.
    1/2. I do not have this data. The best I can do is typical but that would require bench data which I currently do not have.

    What voltage option does your customer need? If you want we can take its to e-mail.
