100 µA fixed output — no adjustment, no surprise
The output is factory-trimmed to 100 µA and is not user-adjustable. If your design needs a different current value, this is not the part; if 100 µA fits, it simplifies the board.

Frequently asked questions
What is the difference between REF200AU and REF200AU/2K5?
The REF200AU/2K5 suffix indicates Tape & Reel packaging (2,500 units per reel) versus the REF200AU which may ship in tube or other formats. The electrical specifications — ±0.25% accuracy, 100 µA output, 2.5V to 40V input — are identical.
Is REF200AU/2K5 a direct replacement for REF200AU?
Yes, the REF200AU/2K5 is electrically identical to the REF200AU. The only difference is the packaging format — Tape & Reel for the /2K5 suffix versus tube for the base part number.
