LM4140CCM-2.5/NOPB

Voltage Reference Overview

The LM4140CCM-2.5/NOPB is a micropower low-dropout series voltage reference manufactured by Texas Instruments, housed in an SOIC-8 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1% and a temperature coefficient of 3 ppm/°C. The device supports a maximum input voltage of 5.6 V and operates within a junction temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Provides high precision voltage regulation with minimal drift over temperature variations
• Features micropower consumption suitable for battery-operated applications
• Includes an enable pin for power management control

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the package type matches the design requirements for surface mount assembly. Ensure the operating temperature range aligns with the intended environmental conditions of the final application.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with high accuracy (0.1%) and low temperature drift (3 ppm/°C) is required. It is suitable for designs prioritizing low power consumption and compact SOIC-8 packaging. Compare against shunt references if current sinking is preferred over series regulation.

Voltage Reference Part Context

This part belongs to the LM4140 family of precision micropower voltage references. It shares architectural similarities with other members like the LM4140ACM variants but differs in specified accuracy grades and temperature coefficients. The family is designed for applications demanding stability and low quiescent current.

Voltage Reference Replacement Considerations

LM4140ACM-2.5/NOPB offers similar functionality with potentially different accuracy or temperature coefficient specifications. Verify electrical parameters and pin compatibility before substitution.
