LM4041DIM3X-1.2/NOPB

Voltage Reference Overview

The LM4041DIM3X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V. It operates within a temperature range of -40°C to +125°C and utilizes an SOT-23 package. The device guarantees an initial accuracy of ±0.5% at 25°C with a maximum operating current of 12 mA and a minimum operating current of 60 µA. It exhibits a load regulation of 8 mV and maintains stability without requiring an external stabilizing capacitor across any capacitive load.

Voltage Reference Feature Summary

• Eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load
• Uses fuse and Zener-zap reverse breakdown or reference voltage trim during wafer sort to ensure high accuracy
• Bandgap reference temperature drift curvature correction ensures stable reverse breakdown voltage accuracy over wide operating ranges

Voltage Reference Applications

• Space-critical applications due to sub-miniature SC70 and SOT-23 surface-mount packages
• Precision measurement systems requiring stable reference voltages
• Battery-powered equipment benefiting from micropower operation

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance as per Texas Instruments documentation. Confirm the 'DIM3X' designation corresponds to the SOT-23 package and tape-and-reel shipping method. Ensure the '-1.2' identifier matches the required 1.225 V fixed output voltage for your circuit design requirements before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is needed in a compact SOT-23 footprint. It is suitable for designs requiring ±0.5% initial accuracy and operation up to +125°C. Consider the 60 µA minimum operating current for low-power applications. Verify that the shunt topology fits the circuit architecture compared to series references.
