The minimum cathode current is 65 µA, so the resistor must be sized to deliver at least that plus the load current at the lowest input voltage. Output current capability is 15 mA maximum, which covers most ADC reference inputs and op-amp bias networks without an external buffer. ## Noise floor and signal-chain fit The SOT-23-3 package (TO-236-3 / SC-59 compatible) keeps the footprint small for portable or multi-channel designs where board space is tight. It is ROHS3 compliant, covering EU and California regulatory requirements without exemption.","metaTitle":"LM4050CEM3-2.5/NOPB Shunt Reference, 2.5V ±0.5%, SOT-23-3","metaDescription":"Texas Instruments LM4050CEM3-2.5/NOPB precision 2.5V shunt voltage reference, ±0.5% tolerance, 50ppm/°C drift, SOT-23-3.
