Questions

Is there a KiCad symbol and footprint for the LM3000ASQ?

Yes. The symbol is EasyEDA_Cloud:LM3000ASQ_NOPB and the footprint EasyEDA_Cloud:WQFN-32_L5.0-W5.0-P0.50-BL-EP3.1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM3000ASQ?

WQFN-32(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the LM3000ASQ datasheet?

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

Where can I order the LM3000ASQ?

JLCPCB lists it as part C3189328, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM3000ASQ?

Parts like it in the library: the LM5119PSQX by Texas Instruments, the LM3000SQ by Texas Instruments, the LM3754SQ by Texas Instruments and the LM5119PSQE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
