Is there a KiCad symbol and footprint for the LM4040C33FTA?
Yes. The symbol is 4ms-vreg:LM4040 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM4040C33FTA?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the LM4040C33FTA datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the LM4040C33FTA?
JLCPCB lists it as part C7216601, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM4040C33FTA?
