Is there a KiCad symbol and footprint for the LM334M?
Yes. The symbol is Regulators:LM334M and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM334M?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM334M datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM334M?
JLCPCB lists it as part C1524129, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM334M?
Parts like it in the library: the LM234DT by STMicroelectronics, the LM334MX by Texas Instruments, the LM334DT by STMicroelectronics and the LM334SMX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM334M?
14 boards in 11 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
