Questions

Is there a KiCad symbol and footprint for the LM5039MH?

Yes. The symbol is EasyEDA_Cloud:LM5039MHX_NOPB and the footprint EasyEDA_Cloud:HTSSOP-20_L6.5-W4.4-P0.65-LS6.4-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM5039MH?

HTSSOP-20-EP, with 21 pins. Its footprint is drawn on this page.

Where is the LM5039MH datasheet?

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

Where can I order the LM5039MH?

JLCPCB lists it as part C1529916, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM5039MH?

Parts like it in the library: the LM5117PMHX by Texas Instruments, the LM5117PMHE by Texas Instruments, the LM5039MHX by Texas Instruments and the LM25118MHE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
