Is there a KiCad symbol and footprint for the LP3874ES-3.3?
Yes. The symbol is EasyEDA_Cloud:LP3874ES-3.3 and the footprint Package_TO_SOT_SMD:TO-263-5_TabPin6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LP3874ES-3.3?
TO-263-5, with 6 pins. Its footprint is drawn on this page.
Where is the LP3874ES-3.3 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LP3874ES-3.3?
JLCPCB lists it as part C139314, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LP3874ES-3.3?
