LM4040DIM3-5.0/NOPB

Overview

The LM4040DIM3-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 5V output with an initial accuracy of ±1%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C. The device features a maximum shunt current of 15mA and a typical temperature coefficient of 150ppm/°C. It is designed for applications requiring precision voltage referencing in space-constrained environments.

Feature Summary

Micropower operation suitable for battery-powered systems
Compact SOT-23-3 surface-mount package design
Fixed 5V precision output capability
Wide operating temperature range support

Applications

Portable instrumentation voltage references
Battery-operated measurement devices
Data acquisition system references
Microcontroller analog-to-digital converter references

Procurement Notes

Verify the specific suffix DIM3X or DIM3 against the required datasheet revision, as packaging variations exist within the LM4040 family. Confirm that the ±1% accuracy meets circuit requirements, as higher precision variants like the B-grade are available. Ensure the 15mA maximum shunt current aligns with the load conditions. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 5V reference is needed in a small footprint. Compare against the LM4040BIM3-5.0/NOPB if tighter ±0.2% accuracy is required. Consider the LM4040CIM3-5.0/NOPB for intermediate performance levels. Evaluate power consumption constraints against the quiescent current specifications. Ensure the thermal management supports 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 DIM3 designation indicates the SOT-23 surface-mount package variant. The NOPB suffix denotes lead-free and rohs compliant construction. This series is widely used in industrial and consumer electronics for stable voltage referencing.

Replacement Considerations

LM4040BIM3-5.0/NOPB offers improved accuracy. LM4040CIM3-5.0/NOPB provides alternative tolerance levels. LM4040DIM3X-5.0/NOPB represents reel packaging variation.
