Questions

Is there a KiCad symbol and footprint for the LM2941CT?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1ADJ_2EN_3GND_4IN_5OUT and the footprint Package_TO_SOT_THT:TO-220-5_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2941CT?

TO-220-5, with 5 pins. Its footprint is drawn on this page.

Where is the LM2941CT datasheet?

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

Where can I order the LM2941CT?

JLCPCB lists it as part C352840, with 49 in stock; the sellers' links on this page open their listings.

What can replace the LM2941CT?

Parts like it in the library: the LM2941TG by HANSCHIP semiconductor, the LM2941T by HGSEMI, the MIC29151T-5.0 by HGSEMI and the MIC39301T-3.3 by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM2941CT?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
