Questions

Is there a KiCad symbol and footprint for the TPS73643DBV?

Yes. The symbol is Regulator_Linear:TPS73643DBV and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TPS73643DBV?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the TPS73643DBV datasheet?

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

Where can I order the TPS73643DBV?

JLCPCB lists it as part C2866025, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TPS73643DBV?

Parts like it in the library: the RN5RF43AA-TR-FE by Nisshinbo Micro Devices Inc., the XC6220B431MR-G by Torex Semiconductor, the S-816A43AMC-BAST2G by ABLIC and the S-816A43AMC-BAST2U by ABLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the TPS73643DBV?

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