Part Number: TL431LI

Tool/software:

Hi Team,

I would like to confirm the temp coefficient calculation, should I refer to the equation in section 8.1 directly? And is the delta TA in the equation 165C(125- - 40)?

Regards,

Charles

    Hi Charles,

    Yes, section 8.1 should give you the correct value for the temperature coefficient for TL431LI. Your understanding of delta TA is correct for the Q version. Please use the temperature range associated with whichever part number you are using:

     

    Thanks,
