Hi,
I use the LP38853, TO220 package in one of my designs. This is an old design.
When I used it, the RθJC(bot) in the datasheet of the TO220 package was 3 C/W.
Now I saw that there is a new datasheet but in the new datasheet, the RθJC(bot) is NA.
Any reason why it was changed to NA ?
Do you know what should be the RθJC(bot) value?
I am attaching the 2 datasheets (old and new)TI LP38853.pdfTI LP38853 new.pdf
