Questions

Is there a KiCad symbol and footprint for the LD1117D33?

Yes. The symbol is EasyEDA_Cloud:LD1117D33TR 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 LD1117D33?

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

Where is the LD1117D33 datasheet?

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

Where can I order the LD1117D33?

JLCPCB lists it as part C2971297, with 1,924 in stock; the sellers' links on this page open their listings.

What can replace the LD1117D33?

Parts like it in the library: the XL1509-3.3 by UMW, the XL1509-3.3E1 by XLSEMI, the LM2675M-3.3(UMW) by UMW and the LM2594HVM-3.3(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LD1117D33?

5 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
