Questions
Is there a KiCad symbol and footprint for the LD2981CU33?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1OUT_2GND_3IN and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LD2981CU33?
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
Where is the LD2981CU33 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LD2981CU33?
JLCPCB lists it as part C222133, with 2,399 in stock; the sellers' links on this page open their listings.
What can replace the LD2981CU33?
Parts like it in the library: the AMS1117-3.3S by UMW, the L78L33ACU by STMicroelectronics, the HT7533-1 by UMW and the AMS1117-3.3 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
