Questions

Is there a KiCad symbol and footprint for the LM317LZ?

Yes. The symbol is Celestial_Power_Linear_VReg:TI LM317L and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317LZ?

TO-92, with 3 pins. Its footprint is drawn on this page.

Where is the LM317LZ datasheet?

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

Where can I order the LM317LZ?

JLCPCB lists it as part C27605, with 4,812 in stock; the sellers' links on this page open their listings.

What can replace the LM317LZ?

Parts like it in the library: the CJ78L09 by Jiangsu Changjing Electronics Technology (CJ), the AS78L05Z-E1 by Diodes Incorporated, the 78L05L by UMW and the LP2950ACZ-5.0 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM317LZ?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
