Questions

Is there a KiCad symbol and footprint for the L79L05ACU?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT 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 L79L05ACU?

SOT-89-3, with 3 pins. Its footprint is drawn on this page.

Where is the L79L05ACU datasheet?

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

Where can I order the L79L05ACU?

JLCPCB lists it as part C157511, with 9,097 in stock; the sellers' links on this page open their listings.

What can replace the L79L05ACU?

Parts like it in the library: the AS78L05RTR-E1 by Diodes Incorporated, the HT7550-1 by UMW, the 78L05 by UMW and the 78L05G-AB3-R by UTC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
