Overview
The 79D12AL-TN3-R is a linear Voltage Regulator made by UTC in a TO-252-2(DPAK) package with 3 pins. 0℃~+125℃ 1 12V 1A 200uV 2V@(1A) 35V 3mA 60dB@(120Hz) Fixed Negative TO-252-2(DPAK) Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:TO-252-2, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C75507).

Is there a KiCad symbol and footprint for the 79D12AL-TN3-R?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_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 79D12AL-TN3-R?
TO-252-2(DPAK), with 3 pins. Its footprint is drawn on this page.
Where is the 79D12AL-TN3-R datasheet?
UTC publishes it: the Datasheet link on this page opens it.
Where can I order the 79D12AL-TN3-R?
JLCPCB lists it as part C75507, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 79D12AL-TN3-R?
Parts like it in the library: the KA7912TU by onsemi and the MC7812CD2TG by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
