Adjustable shunt reference — 1.233 V minimum, 10 V ceiling
It delivers up to 12 mA output current with a cathode current floor of 65 µA, making it suitable for biasing precision analog circuits, ADC/DAC references, and power supply feedback loops where a stable, low-noise voltage is needed.
±0.5 % tolerance and 100 ppm/°C drift — the accuracy budget
Initial output tolerance is ±0.5 %, which sets the uncalibrated accuracy floor for the reference voltage. The temperature coefficient of 100 ppm/°C means the output shifts by roughly 0.5 mV over a 40°C swing at a 1.233 V set point — acceptable for 8- to 10-bit systems but a design consideration for 12-bit applications without calibration. Noise is specified at 20 µVrms over a 10 Hz to 10 kHz bandwidth, which is low enough to avoid swamping the LSB of a 12-bit ADC with a 2.5 V reference.
Obsolete — sourcing from independent distribution
Buyers should verify date-code freshness and request traceability documentation as part of the procurement process.
SOT-23-3 footprint and pin compatibility
Packaged in a three-lead SOT-23-3 (also listed as TO-236-3 or SC-59), this is a standard surface-mount footprint shared by dozens of shunt references from multiple manufacturers. The pin arrangement — cathode, anode, and no-connect (or adjust) — follows the common LM4041 pinout, making it a drop-in candidate for boards originally designed with other adjustable shunt references in the same package.
