Questions
Is there a KiCad symbol and footprint for the LK112M18?
Yes. The symbol is Regulator_Linear:LK112M18TR and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LK112M18?
SOT-23-5L, with 5 pins. Its footprint is drawn on this page.
Where is the LK112M18 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LK112M18?
JLCPCB lists it as part C2971117, with 46 in stock; the sellers' links on this page open their listings.
What can replace the LK112M18?
Parts like it in the library: the AP2112K-1.8TRG1 by Diodes Incorporated, the ME6211C18M5G-N by MICRONE, the RT9078-18GJ5 by RICHTEK and the LP5907MFX-1.8 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
