Questions

Is there a KiCad symbol and footprint for the MIC2178YWM-TR?

Yes. The symbol is Regulator_Switching:MIC2178 and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MIC2178YWM-TR?

SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.

Where is the MIC2178YWM-TR datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the MIC2178YWM-TR?

JLCPCB lists it as part C632071, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MIC2178YWM-TR?

Parts like it in the library: the L4973D5.1-013 by STMicroelectronics, the LT1269CSW#TRPBF by Analog Devices, the LT1371CSW#PBF by Analog Devices and the LT1371HVCSW#PBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
