Questions
Is there a KiCad symbol and footprint for the LR7812?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-220-3_L10.2-W4.6-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LR7812?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the LR7812 datasheet?
Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.
Where can I order the LR7812?
JLCPCB lists it as part C2887403, with 3 in stock; the sellers' links on this page open their listings.
What can replace the LR7812?
Parts like it in the library: the LM7912AL-TA3-T by UTC, the BA12T by ROHM Semiconductor, the BA17812T by ROHM Semiconductor and the CJ7812 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
