Questions
Is there a KiCad symbol and footprint for the LR8K4-G?
Yes. The symbol is Regulator_Linear:LR8K4-G and the footprint Package_TO_SOT_SMD:TO-252-2, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LR8K4-G?
TO-252-2(DPAK), with 3 pins. Its footprint is drawn on this page.
Where is the LR8K4-G datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the LR8K4-G?
JLCPCB lists it as part C145584, with 2 in stock; the sellers' links on this page open their listings.
What can replace the LR8K4-G?
Parts like it in the library: the L78M05CDT-TR by STMicroelectronics, the CJ78M05 by Jiangsu Changjing Electronics Technology (CJ), the L78M05CDT-TR(JSM) by JSMSEMI and the CJ7805 3% by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LR8K4-G?
10 boards in 8 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
