Questions
Is there a KiCad symbol and footprint for the AMS1117?
Yes. The symbol is Regulator_Linear:AMS1117 and the footprint Package_TO_SOT_SMD:SOT-223-3_TabPin2, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the AMS1117 datasheet?
Advanced Monolithic Systems publishes it: the Datasheet link on this page opens it.
What can replace the AMS1117?
Parts like it in the library: the AMS1117-3.3OE by GREENMICRO, the LM1117-3.3 by hongjiacheng, the AMS1117-5.0OE by GREENMICRO and the AZ1117CH2-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the AMS1117?
335 boards in 250 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
