Questions

Is there a KiCad symbol and footprint for the LD1086DTTRY?

Yes. The symbol is Regulator_Linear:LD1086DTTR 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 LD1086DTTRY?

DPAK, with 3 pins. Its footprint is drawn on this page.

Where is the LD1086DTTRY datasheet?

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

Where can I order the LD1086DTTRY?

JLCPCB lists it as part C2802526, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LD1086DTTRY?

Parts like it in the library: the CJ7805 3% by Jiangsu Changjing Electronics Technology (CJ), the UZ1085L-33-TN3-R by UTC, the AMS1086CD-3.3 by Advanced Monolithic Systems and the CJ7908 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
