Questions

Is there a KiCad symbol and footprint for the LD1117AS33?

Yes. The symbol is Celestial_Power_Linear_VReg:ST LD1117 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 LD1117AS33?

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

Where is the LD1117AS33 datasheet?

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

Where can I order the LD1117AS33?

JLCPCB lists it as part C115288, with 40,571 in stock; the sellers' links on this page open their listings.

What can replace the LD1117AS33?

Parts like it in the library: the LR1117CS33X by Leshan Radio (LRC), the JY1117E33AX by Shenzhen JingYang, the ZD1117ILTR33 by Zetta and the ADP3338AKCZ-3.3RL7 by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LD1117AS33?

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