Questions

Is there a KiCad symbol and footprint for the L5986A?

Yes. The symbol is EasyEDA_Cloud:L5985TR and the footprint EasyEDA_Cloud:HSOP-8_L5.0-W4.0-P1.27-LS6.2-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L5986A?

HSOP-8-EP, with 9 pins. Its footprint is drawn on this page.

Where is the L5986A datasheet?

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

Where can I order the L5986A?

JLCPCB lists it as part C2073192, with 10 in stock; the sellers' links on this page open their listings.

What can replace the L5986A?

Parts like it in the library: the L5973D013 by STMicroelectronics, the TPS54327DDAR by Texas Instruments, the TPS5432DDAR by Texas Instruments and the TPS54428DDAR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
