Housed in a SOT-23-3 package, it operates over the full industrial temperature range of -40°C to 125°C, making it suitable for automotive, industrial control, and instrumentation applications where a stable reference voltage is required for ADC/DAC biasing, comparator thresholds, or power supply monitoring. ## Shunt topology — what it means for the BOM As a shunt reference, the LM4050AEM3-10/NOPB behaves like a precision Zener diode: it requires a series resistor from the supply to bias the cathode with at least 110 µA (the minimum cathode current) while the output can source up to 15 mA to the load. This topology is simple and robust — no separate supply pin, and the reference can sink current from a higher-voltage rail. The trade-off is that the series resistor must be sized to maintain the minimum cathode current across the full load and supply range, which adds a design step compared to a series reference. ## Active production — no LTB risk No last-time-buy windows or obsolescence notices are in effect, so it can be specified into new designs with confidence. The part is ROHS3 compliant and available in Tape & Reel or Cut Tape for prototyping or production.","metaTitle":"LM4050AEM3-10/NOPB Shunt Voltage Reference","metaDescription":"TI LM4050AEM3-10/NOPB precision shunt voltage reference, fixed 10V output, ±0.1% tolerance, 50ppm/°C drift, SOT-23-3, -40°C to 125°C.
