LM4040BIM3-10.0/NOPB

Overview

The LM4040BIM3-10.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 10 V with an initial accuracy of ±0.5%. Housed in a compact SOT-23-3 surface-mount package, it operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA.

Feature Summary

• Micropower operation suitable for battery-powered applications
• High precision with low temperature coefficient
• Compact three-pin SOT-23 surface-mount packaging

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-operated measurement systems
• Data acquisition systems needing precise analog references

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance as per manufacturer documentation. Confirm the 'B' grade corresponds to the ±0.5% accuracy specification. Ensure the SOT-23-3 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 10 V reference is required in space-constrained designs. The ±0.5% tolerance offers a balance between cost and precision. Consider the 15 mA maximum current limit for load requirements and ensure the operating environment stays within the specified -40°C to +85°C range.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It serves as a stable reference element in linear regulator circuits and ADC/DAC front ends. The device utilizes a bandgap reference architecture to maintain stability across varying temperatures and supply conditions.

Replacement Considerations

LM4040CIM3-10.0/NOPB (±0.5% accuracy) and LM4040DIM3-10.0/NOPB (±1% accuracy) are compatible alternatives within the same package and family.
