Questions

Is there a KiCad symbol and footprint for the LM4940TSX?

Yes. The symbol is EasyEDA_Cloud:LM4940TSX_NOPB and the footprint Package_TO_SOT_SMD:TO-263-9_TabPin10, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4940TSX?

TO-263-9, with 10 pins. Its footprint is drawn on this page.

Where is the LM4940TSX datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM4940TSX?

JLCPCB lists it as part C2877269, with 186 in stock; the sellers' links on this page open their listings.

What can replace the LM4940TSX?

Parts like it in the library: the LM4952TS by Texas Instruments and the LM4952TSX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
