The Texas Instruments LM4040CIM3X-8.2/NOPB is a precision shunt voltage reference that delivers a fixed 8.192 V output with a ±0.5% initial tolerance. The shunt architecture means it operates like a two-terminal Zener — the load and the bias resistor share the same current path, so the 15 mA maximum output current and the 95 µA minimum cathode current together define the resistor value and the power budget.
