Questions

Is there a KiCad symbol and footprint for the LM7805S?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_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 LM7805S?

TO-263-3, with 4 pins. Its footprint is drawn on this page.

Where is the LM7805S datasheet?

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

Where can I order the LM7805S?

JLCPCB lists it as part C2873102, with 14 in stock; the sellers' links on this page open their listings.

What can replace the LM7805S?

Parts like it in the library: the AMS1084CM-5.0 by Advanced Monolithic Systems, the LM1085ISX-5.0 by Texas Instruments, the LM1084S-5.0/TR by HGSEMI and the LM1085S-5.0/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM7805S?
