LMV431BIMF/NOPB

Voltage Reference Overview

The LMV431BIMF/NOPB is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 30 V and features a 0.5% initial tolerance. The device supports a maximum cathode current of 15 mA and withstands a maximum series voltage of 35 V. It functions reliably across a temperature range of -40°C to +85°C and is housed in a SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

• Provides low-voltage operation with a wide adjustment range from 1.24 V to 30 V
• Delivers high precision with 0.5% initial tolerance for accurate reference applications
• Temperature compensated for industrial environments ensuring stable performance

Voltage Reference Applications

• Precision voltage references in battery-powered systems
• Adjustable power supply regulation circuits
• Comparator reference voltage generation

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the 'IMF' designation corresponds to the SOT-23-3 package variant. Ensure the ordering part number matches the required 0.5% tolerance grade (LMV431B) rather than standard variants. Cross-reference the datasheet revision date to confirm technical specifications remain unchanged.

Voltage Reference Selection Notes

Select this component when a low-voltage, high-precision shunt regulator is required in a compact surface-mount footprint. The 0.5% tolerance distinguishes it from standard versions, making it suitable for applications demanding tighter accuracy. Consider the 15 mA current limit and 35 V maximum voltage rating during circuit design to ensure safe operating margins are maintained under all load conditions.

Voltage Reference Part Context

This device belongs to the LMV431x family of low-voltage adjustable precision shunt regulators. It serves as a drop-in replacement for traditional Zener diodes in many reference applications, offering superior stability and lower noise characteristics. The NOPB suffix denotes a lead-free and environmentally friendly product compliant with international standards.

Voltage Reference Replacement Considerations

Direct substitutes include other LMV431B variants such as LMV431BIQ/NOPB or LMV431BIDR/NOPB, provided the package type matches the design constraints. Verify that alternative components maintain the 0.5% initial tolerance specification to ensure circuit accuracy is preserved without redesign.
