Questions

Is there a KiCad symbol and footprint for the LP2951CD?

Yes. The symbol is EasyEDA_Pro:LP2951CDR2G 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 LP2951CD?

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

Where is the LP2951CD datasheet?

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

Where can I order the LP2951CD?

JLCPCB lists it as part C7987, with 6,400 in stock; the sellers' links on this page open their listings.

What can replace the LP2951CD?

Parts like it in the library: the L78L05ACD13 by STMicroelectronics, the L78L05ABD13 by STMicroelectronics, the L78L33ACD13 by STMicroelectronics and the LM317LID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
