Is there a KiCad symbol and footprint for the LD39015M10R?
Yes. The symbol is Regulator_Linear:LD39015M10R 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 LD39015M10R?
SOT-23-5L, with 5 pins. Its footprint is drawn on this page.
Where is the LD39015M10R datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LD39015M10R?
JLCPCB lists it as part C221497, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LD39015M10R?
Parts like it in the library: the TLV73310PDBV by Texas Instruments, the AP7335-10WG by Diodes Incorporated, the TLV74310PDBV by Texas Instruments and the TLV75710PDBV by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
