Questions

Is there a KiCad symbol and footprint for the LM2735XMF?

Yes. The symbol is Regulator_Switching:LM2735XMF and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2735XMF?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the LM2735XMF datasheet?

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

Where can I order the LM2735XMF?

JLCPCB lists it as part C2070665, with 134 in stock; the sellers' links on this page open their listings.

What can replace the LM2735XMF?

Parts like it in the library: the ETA3409S2F by etasolution, the ETA3417S2F by etasolution, the RY3430 by RYCHIP Semiconductor Inc. and the ETA3418S2F by etasolution. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM2735XMF?

7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
