The bias resistor from the supply to the cathode must be chosen so that the cathode current stays above 68 µA at the minimum supply voltage and maximum load. The /NOPB suffix confirms lead-free (RoHS-compliant) construction.","metaTitle":"LM4041CEM3-ADJ/NOPB Shunt Voltage Reference","metaDescription":"TI LM4041CEM3-ADJ/NOPB shunt voltage reference, adjustable output 1.233 V to 10 V, ±0.5% tolerance, SOT-23-3, -40°C to 125°C.
