Questions

Is there a KiCad symbol and footprint for the LDL1117?

Yes. The symbol is Celestial_Power_Linear_VReg:ST LDL1117 and the footprint Horizon_sot:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the LDL1117 datasheet?

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

What can replace the LDL1117?

Parts like it in the library: the AMS1117D-1.2RG by HANSCHIP semiconductor, the AMS1117D-1.5RG by HANSCHIP semiconductor, the AMS1117D-5.0RG by HANSCHIP semiconductor and the AMS1117D-ADJRG by HANSCHIP semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LDL1117?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
