Questions

Is there a KiCad symbol and footprint for the LM317MBDT?

Yes. The symbol is tinkerforge:LM317M 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 LM317MBDT?

TO-252-2(DPAK), with 3 pins. Its footprint is drawn on this page.

Where is the LM317MBDT datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the LM317MBDT?

JLCPCB lists it as part C179570, with 9,321 in stock; the sellers' links on this page open their listings.

What can replace the LM317MBDT?

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.
