1.225V fixed output with ±0.2% tolerance
The 20 µVrms noise spec (10 Hz to 10 kHz) is clean enough for 12-bit ADC references and precision comparator thresholds in industrial control and instrumentation.
Current ratings and bias requirements
The shunt reference sinks up to 12 mA of output current — enough to bias a handful of op-amp inputs or a low-power ADC reference input. Below 65 µA the reference may drop out of regulation; above 12 mA the device dissipates excess power as heat. The SOT-23-3 package has limited thermal mass.
SOT-23-3 rework and board fit
The small body and low thermal mass make it easy to hand-rework with hot air. No exposed pad, so no thermal-via requirement under the part.
