Questions
Is there a KiCad symbol and footprint for the LM2940CS-12?
Yes. The symbol is Regulators:REG3+1 1IN-2GND-3OUT+4GND 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-12?
TO-263-3, with 4 pins. Its footprint is drawn on this page.
Where is the LM2940CS-12 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM2940CS-12?
JLCPCB lists it as part C2865267, with 2 in stock; the sellers' links on this page open their listings.
What can replace the LM2940CS-12?
Parts like it in the library: the LM1085IS-12/NOPB by Texas Instruments, the LM7812SX by Texas Instruments, the LM340S-12/TR by HGSEMI and the LM2940SX-12 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
