LM317: Junction to ambient thermal resistance of LM317 - To 252 package and part number is LM317MKVURG3

Arvind Tapse75

Part Number: LM317

We are planning to use the LM317 and complete part number is LM317MKVURG3.

https://www.ti.com/lit/ds/symlink/lm317m.pdf

 I am going through the datasheet but not able to see thermal information like below for the TO-252 package. Would you please share this information? Specially, I need Junction to ambient thermal resistance for TO-252 package. Please share this info asap.

 Thanks.

Best regards,

    Hi Arvind,

    I pulled this data internally, it did not come from a datasheet.

    We have this documented in our datasheet correction log, however we have not yet updated the datasheet with the numbers I provided you.

    Thanks,
