Questions

Is there a KiCad symbol and footprint for the REG1117?

Yes. The symbol is EasyEDA_Cloud:REG1117-5 and the footprint EasyEDA_Cloud:SOT-223-4_L6.5-W3.5-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the REG1117?

SOT-223-4, with 4 pins. Its footprint is drawn on this page.

Where is the REG1117 datasheet?

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

Where can I order the REG1117?

JLCPCB lists it as part C2867217, with 0 in stock; the sellers' links on this page open their listings.

What can replace the REG1117?

Parts like it in the library: the SPX1117M3-L-3-3/TR by MaxLinear, the LD1117AS33 by STMicroelectronics, the SPX1117M3-L-5-0/TR by MaxLinear and the LD1117-ADJ by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the REG1117?

15 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
