Questions
Is there a KiCad symbol and footprint for the LDF33DT-TR?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2OUT_3GND and the footprint EasyEDA_Cloud:TO-252-3_L6.6-W6.1-P4.56-LS9.9-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LDF33DT-TR?
DPAK, with 3 pins. Its footprint is drawn on this page.
Where is the LDF33DT-TR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LDF33DT-TR?
JLCPCB lists it as part C2965357, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LDF33DT-TR?
Parts like it in the library: the AMS1117-3.3 by Advanced Monolithic Systems, the AMS1117-3.3 by UMW, the AMS1117-3.3V by MSKSEMI and the AMS1117-3.3S by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
