Questions
Is there a KiCad symbol and footprint for the LP2951D?
Yes. The symbol is Celestial_Power_Linear_VReg:TI LP2951D 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 LP2951D?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LP2951D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LP2951D?
JLCPCB lists it as part C414606, with 1,349 in stock; the sellers' links on this page open their listings.
What can replace the LP2951D?
Parts like it in the library: the L78L05ACD13 by STMicroelectronics, the L78L05ABD13 by STMicroelectronics, the LM78L05ACMX by Texas Instruments and the MC78L05ABD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LP2951D?
11 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
