Questions
Is there a KiCad symbol and footprint for the LM317LD?
Yes. The symbol is EasyEDA_Cloud:LM317LD13TR and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM317LD?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM317LD datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the LM317LD?
JLCPCB lists it as part C3029046, with 6,833 in stock; the sellers' links on this page open their listings.
What can replace the LM317LD?
Parts like it in the library: the LM78L05ACM/TR by HGSEMI, the AS78L05MTR-G1 by Diodes Incorporated, the SSP7786A-3.3V by Shanghai Siproin Microelectronics and the SM7033P by Shenzhen Sunmoon Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM317LD?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
