Questions

Is there a KiCad symbol and footprint for the LM317LMX?

Yes. The symbol is EasyEDA_Cloud:LM317DRG 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 LM317LMX?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM317LMX datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM317LMX?

JLCPCB lists it as part C388285, with 41,171 in stock; the sellers' links on this page open their listings.

What can replace the LM317LMX?

Parts like it in the library: the L78L05ACD13 by STMicroelectronics, the L78L05ABD13 by STMicroelectronics, the L78L33ACD13 by STMicroelectronics and the LM317LID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM317LMX?

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