Questions

Is there a KiCad symbol and footprint for the L7986ATR?

Yes. The symbol is EasyEDA_Cloud:L7986ATR and the footprint EasyEDA_Cloud:ESOP-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L7986ATR?

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

Where is the L7986ATR datasheet?

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

Where can I order the L7986ATR?

JLCPCB lists it as part C157370, with 4,607 in stock; the sellers' links on this page open their listings.

What can replace the L7986ATR?

Parts like it in the library: the ETA2808E8A by etasolution, the SCT2432STER by SCT, the SCT2630ASTER by SCT and the SCT9336STER by SCT. Check their datasheets: a part that fits the footprint may still differ in its ratings.
