Is there a KiCad symbol and footprint for the L78M12CV?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L78M12CV?
TO-220-3, with 3 pins. Its footprint is drawn on this page.
Where is the L78M12CV datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L78M12CV?
JLCPCB lists it as part C2965430, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L78M12CV?
Parts like it in the library: the LM317 by Jiangsu Changjing Electronics Technology (CJ), the L7812CV-JSM by JSMSEMI, the LD1117V33 by STMicroelectronics and the LD1117V33C by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the L78M12CV?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
