Is there a KiCad symbol and footprint for the LM317?
Yes. the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM317?
SOT-223, with 4 pins. Its footprint is drawn on this page.
Where is the LM317 datasheet?
RealChip publishes it: the Datasheet link on this page opens it.
Where can I order the LM317?
JLCPCB lists it as part C22399960, with 210 in stock; the sellers' links on this page open their listings.
What can replace the LM317?
Parts like it in the library: the GM317AEMP by GREENMICRO, the FZT749 by Diodes Incorporated, the LM317G by GOODWORK and the LM317AG-JSM by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
