As a shunt (two-terminal) reference, it behaves like a precision Zener diode: you set the bias current with a single resistor from the supply rail to the cathode. The 65 µA minimum cathode current sets the upper limit on that resistor value; the 15 mA maximum output current defines the load it can drive while staying in regulation. ## Noise floor and output current — fit for precision analog rails Output noise is specified at 35 µVrms over the 10 Hz to 10 kHz band — low enough that a 16-bit ADC with a 2.5 V reference input sees less than 0.5 LSB of reference noise contribution. The 15 mA output current can simultaneously bias an op-amp front-end and provide the reference voltage to an ADC, eliminating a separate buffer stage. The fixed 2.5 V output matches the common full-scale input of many SAR and delta-sigma ADCs. No external divider resistors are needed, saving two components and the associated drift path. ROHS3 compliant per the manufacturer's declaration.","metaTitle":"LM4050BEX3-2.5+T Shunt Reference, 2.5V ±0.2%, SC-70","metaDescription":"Analog Devices LM4050BEX3-2.5+T precision shunt voltage reference, 2.5V fixed output, ±0.2% tolerance, 50ppm/°C, SC-70-3.
