LM4040CIM3-5.0-T

Overview

The LM4040CIM3-5.0-T is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 ppm/°C. Packaged in a compact SOT-23-3 (SC-70-3) surface-mount case, it supports a maximum shunt current of 15 mA and draws a quiescent current of approximately 45 µA.

Feature Summary

Micropower operation with low quiescent current consumption suitable for battery-powered applications
High precision performance with tight initial accuracy tolerance
Compact surface-mount packaging designed for space-constrained circuit designs

Applications

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

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated for this specific part number. Confirm the package type is SOT-23-3 and the output voltage is fixed at 5 V. Ensure the accuracy grade matches the required ±0.5% specification for your design. Check RoHS compliance status if environmental regulations apply to your project requirements.

Selection Notes

Select this component when a stable 5 V reference is needed in a small footprint. The SOT-23-3 package offers a balance between size and thermal performance. Consider the 100 ppm/°C temperature coefficient for environments with significant thermal variations. The micropower characteristic makes it ideal for extending battery life in portable devices compared to higher current alternatives.

Part Context

This component belongs to the LM4040 series of improved precision micropower shunt voltage references. The series includes various output voltages and accuracy grades packaged in SOT-23 and SC-70 formats. These references are widely used in power management and signal conditioning circuits where a reliable voltage baseline is critical for accurate operation.
