LMV431IM5/NOPB

Voltage Reference Overview

The LMV431IM5/NOPB is a low-voltage adjustable shunt voltage reference manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 30 V and features an initial accuracy of 1.5%. The device supports a maximum shunt current of 15 mA and withstands a maximum series input voltage of 35 V. It exhibits a temperature coefficient of 138 ppm/°C and functions reliably between -40°C and +85°C. Packaged in a surface-mount SOT-23-5 format, it serves as a precision reference for power management applications.

Voltage Reference Feature Summary

• Provides adjustable voltage referencing with a minimum output of 1.24 V
• Operates as a shunt regulator with high input voltage tolerance up to 35 V
• Delivers stable performance across a wide industrial temperature range

Voltage Reference Applications

• Portable equipment requiring precise voltage monitoring
• Battery-powered systems needing accurate reference levels
• General-purpose power supply regulation circuits

Voltage Reference Procurement Notes

Verify the specific suffix NOPB confirms lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm the SOT-23-5 package marking and pinout alignment with your PCB footprint design. Ensure the 1.5% initial accuracy specification meets your circuit tolerance requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable shunt reference is required for space-constrained designs. The SOT-23-5 package offers a compact solution compared to larger through-hole alternatives. Consider the 1.5% accuracy and 138 ppm/°C temperature coefficient to ensure they align with the precision demands of your specific application environment.

Voltage Reference Part Context

This part belongs to the LMV431 family of low-voltage adjustable shunt references from Texas Instruments. It shares functional similarities with other members like the LMV431AIMFX/NOPB but differs in initial accuracy specifications. The family is designed for cost-sensitive applications where moderate precision is sufficient for voltage regulation tasks.

Voltage Reference Replacement Considerations

LMV431ACM5/NOPB offers 1% accuracy in the same SOT-23-5 package. LMV431AIMFX/NOPB provides 1% accuracy in an SOT-23-3 package.
