Questions

Is there a KiCad symbol and footprint for the L6982NDR?

Yes. The symbol is EasyEDA_Cloud:L6982N33DR and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6982NDR?

SO-8, with 8 pins. Its footprint is drawn on this page.

Where is the L6982NDR datasheet?

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

Where can I order the L6982NDR?

JLCPCB lists it as part C3192321, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L6982NDR?

Parts like it in the library: the XL1509-5.0E1 by XLSEMI, the XL1509-ADJE1 by XLSEMI, the XL1410E1 by XLSEMI and the TPS54231D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
