The Texas Instruments LM4041B12IDCKR is a precision shunt voltage reference that delivers a fixed 1.225 V output with ±0.2% initial tolerance.
The shunt reference can source up to 12 mA of output current while drawing a minimum cathode current of 80 µA for stable regulation.
Yes. As a shunt reference, it operates from any supply voltage above 1.225 V plus the headroom needed for the series resistor. A 3.3 V rail works fine as long as the resistor is chosen to maintain at least 80 µA cathode current at the maximum load.
