Questions

Is there a KiCad symbol and footprint for the LM2940G-50-AA3-R?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT_4GND and the footprint EasyEDA_Cloud:SOT-223-4_L6.5-W3.5-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2940G-50-AA3-R?

SOT-223-4, with 4 pins. Its footprint is drawn on this page.

Where is the LM2940G-50-AA3-R datasheet?

UTC publishes it: the Datasheet link on this page opens it.

Where can I order the LM2940G-50-AA3-R?

JLCPCB lists it as part C71094, with 2,633 in stock; the sellers' links on this page open their listings.

What can replace the LM2940G-50-AA3-R?

Parts like it in the library: the GN1117-5.0V by GN Semic, the ZLDO1117QG50TA by Diodes Incorporated, the IL1117C-5.0 by IKSEMICON and the BL8072CLTR50 by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
