Is there a KiCad symbol and footprint for the LM2940CS-15?
Yes. The symbol is EasyEDA_Cloud:LT1963EST-1.8#PBF and the footprint Package_TO_SOT_SMD:TO-263-3_TabPin4, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2940CS-15?
TO-263-3, with 4 pins. Its footprint is drawn on this page.
Where is the LM2940CS-15 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM2940CS-15?
JLCPCB lists it as part C2862551, with 13 in stock; the sellers' links on this page open their listings.
What can replace the LM2940CS-15?
Parts like it in the library: the LM7815SRG by HANSCHIP semiconductor, the LM7815S/TR by HGSEMI, the LM7915S/TR by HGSEMI and the LM2990S-15 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
