Product details

Shunt reference for 2.048V rails — TO-92-3 through-hole

The Texas Instruments LM4040DIZ-2.0/NOPB is a precision shunt voltage reference delivering a fixed 2.048V output with ±1% initial tolerance. It operates as a two-terminal shunt — no external series resistor is needed, but the cathode current must be set by a bias resistor to the supply rail. The 70 µA minimum cathode current keeps the reference in regulation at light loads, while the 15 mA maximum output current defines the load budget for driving ADC reference inputs, comparator thresholds, or low-power bias rails.
