Questions

Is there a KiCad symbol and footprint for the LM2991T?

Yes. The symbol is EasyEDA_Cloud:LM2991T_NOPB 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 LM2991T?

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

Where is the LM2991T datasheet?

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

Where can I order the LM2991T?

JLCPCB lists it as part C2860450, with 386 in stock; the sellers' links on this page open their listings.

What can replace the LM2991T?

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 LM2991T?

3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
