Overview
The REF200AU is a current Source , Constant Current Source made by Texas Instruments in a SOIC-8 package with 8 pins. -25℃~+85℃ 100uA 2.5V~40V Current Source ±0.25% SOIC-8 Current Source / Constant Current Source ROHS.
PCBKit's library has its KiCad symbol (Reference_Current:REF200AU, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1524133). 2 open-source boards in 2 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the REF200AU?
Yes. The symbol is Reference_Current:REF200AU and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the REF200AU?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the REF200AU datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the REF200AU?
JLCPCB lists it as part C1524133, with 0 in stock; the sellers' links on this page open their listings.
What can replace the REF200AU?
Parts like it in the library: the REF200AU/2K5 by Texas Instruments, the LM334S8#PBF by Analog Devices and the LM334S8#TRPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the REF200AU?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
