Questions

Is there a KiCad symbol and footprint for the L7812ABV?

Yes. The symbol is Regulator_Linear:L7812 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 L7812ABV?

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

Where is the L7812ABV datasheet?

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

Where can I order the L7812ABV?

JLCPCB lists it as part C29119, with 4,540 in stock; the sellers' links on this page open their listings.

What can replace the L7812ABV?

Parts like it in the library: the MC7912BT by onsemi, the LM7812T by HGSEMI, the 7812 by HXY MOSFET and the L7812CV by Minos. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the L7812ABV?

2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
