Product details

1.225V fixed shunt reference with AEC-Q100 qualification

The LM4041QEIM3-1.2/NO is a precision shunt voltage reference from Texas Instruments, delivering a fixed 1.225V output with ±2% initial tolerance.

Shunt architecture — no load-current ceiling to manage

As a shunt reference, the LM4041QEIM3-1.2/NO sinks current through its cathode to regulate the output voltage. The minimum cathode current is 70 µA, which sets the lower bound for the series resistor calculation. Maximum output current is 12 mA, so the total current through the device plus any external load must stay under that ceiling to maintain regulation.

SOT-23-3 footprint and supply posture

The three-pin layout — cathode, anode, and no-connect — matches the industry-standard shunt reference pinout used across the LM4041 family.

Frequently asked questions

Is LM4041QEIM3-1.2/NO automotive qualified?

Yes, it carries Automotive, AEC-Q100 qualification, making it suitable for production in automotive-grade assemblies that require PPAP-level device traceability.
