Questions

Is there a KiCad symbol and footprint for the L78S05CV?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L78S05CV?

TO-220, with 3 pins. Its footprint is drawn on this page.

Where is the L78S05CV datasheet?

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

Where can I order the L78S05CV?

JLCPCB lists it as part C33043, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L78S05CV?

Parts like it in the library: the LD1085V50 by STMicroelectronics, the LM1084IT-5.0 by Texas Instruments, the LT1085CT-5#PBF by Analog Devices and the LT1085IT-5#PBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the L78S05CV?

7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
