LM4040CEM3-3.0/NOPB

Overview

The LM4040CEM3-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3.0 V with an initial accuracy of ±1%. Packaged in the compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C. The device draws a typical cathode current of 67 µA and supports a maximum load current of 15 mA. It features a temperature coefficient of 150 ppm/°C and meets RoHS standards without halogen.

Feature Summary

Provides stable precision voltage reference using shunt topology
Designed for low power consumption applications
Suitable for space-constrained surface-mount designs

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable references
Handheld meters and test equipment

Procurement Notes

Verify the specific suffix EM3 indicates the SOT-23-3 package variant. Confirm the CE designation aligns with the required ±1% tolerance grade. Ensure the NOPB suffix confirms lead-free and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.0 V reference is needed with moderate precision. Compare against higher accuracy grades like AIM3 or BIM3 if tighter tolerances are required. Consider the SOT-23-3 footprint constraints and thermal performance within the specified operating temperature range.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040 family is widely used in general-purpose analog circuits where stability and low cost are prioritized over ultra-high precision.

Replacement Considerations

LM4040BEM3-3.0/NOPB offers improved accuracy. LM4040AEM3-3.0/NOPB provides the highest precision in this package. Verify pinout compatibility and thermal characteristics when substituting.
