Tolerance holds to ±0.5%, and the temperature coefficient is rated at 25 ppm/°C, so the output stays within a few millivolts across the full -40°C to 85°C industrial temperature range. This makes it a clean reference for an ADC's Vref pin, a comparator threshold divider, or a low-drift bias rail in a sensor signal chain. Output current capability is 15 mA, and the shunt cathode current sits at 60 µA — low enough to keep the power budget tight in battery-powered or energy-harvesting designs. The reference type is shunt, meaning it operates like a precision Zener: it sinks current through an external resistor from a higher supply rail, regulating the voltage at the cathode. No separate bias supply is needed. Package is the SC-70-3 (SOT-323 footprint), a 3-pin surface-mount case. ## Active production — no LTB clock ticking The MAX6138CEXR12+T carries an Active lifecycle status from the manufacturer.
