Is there a KiCad symbol and footprint for the L78L09ACU?
Yes. The symbol is EasyEDA_Cloud:AD1583CRTZ-REEL7 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 L78L09ACU?
SOT-89, with 3 pins. Its footprint is drawn on this page.
Where is the L78L09ACU datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L78L09ACU?
JLCPCB lists it as part C377943, with 671 in stock; the sellers' links on this page open their listings.
What can replace the L78L09ACU?
Parts like it in the library: the LR78L09A by Leshan Radio (LRC), the 78L09-150 by UMW, the 78L09 by HXY MOSFET and the 78L09T by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
