Adjustable shunt reference in a small SOT-23-5
The LMV431CM5X: Rated for 15 mA continuous output current and a maximum cathode current of 80 µA, this part suits low-power bias and regulation loops in commercial-temperature (0°C to 70°C) designs.
Output range and tolerance for the BOM
The adjustable output spans from 1.24V up to 30V, set by two external resistors — the ±1.5% initial tolerance means the reference voltage at the set point stays within that band without trimming. With an 80 µA minimum cathode current, the LMV431CM5X draws less bias than the classic TL431 (which needs 1 mA minimum), making it a better fit for battery-powered or low-headroom supplies where every microamp counts.
Note that this part is RoHS non-compliant, so it is not suitable for assemblies that must meet EU RoHS exemption-free requirements; confirm your exemption status before specifying.
