Questions

Is there a KiCad symbol and footprint for the LF33CDT-TR?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint Package_TO_SOT_SMD:TO-252-2, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LF33CDT-TR?

TO-252-2(DPAK), with 3 pins. Its footprint is drawn on this page.

Where is the LF33CDT-TR datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LF33CDT-TR?

JLCPCB lists it as part C222179, with 3,789 in stock; the sellers' links on this page open their listings.

What can replace the LF33CDT-TR?

Parts like it in the library: the L78M05CDT-TR by STMicroelectronics, the CJ78M05 by Jiangsu Changjing Electronics Technology (CJ), the L78M05CDT-TR(JSM) by JSMSEMI and the CJ7805 3% by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LF33CDT-TR?

5 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
