For a 12-bit ADC with a 2.5 V full-scale, that tolerance translates to roughly ±8 LSB of absolute error — acceptable for many industrial control loops but marginal for high-accuracy metering without calibration. The device can source up to 10 mA of output current while maintaining regulation, and requires a minimum cathode current of 400 µA to stay in the shunt active region. In low-power designs, the bias resistor must be sized so the sum of the load current and the 400 µA cathode current does not drop the cathode voltage below the 2.49 V threshold at the minimum supply voltage. ## Commercial temperature grade — not for under-hood or industrial If your BOM calls for -40°C operation, look at the LM336Z-2.5 in TO-92 or an automotive-grade shunt reference.","metaTitle":"TI LM336BMX-2.5/NOPB Voltage Reference, ±2%, 2.49V Fixed","metaDescription":"TI LM336BMX-2.5/NOPB precision shunt voltage reference with ±2% tolerance, 2.49V fixed output, 10 mA output current.
