LMV431ACM5-TI

Voltage Reference Overview

The LMV431ACM5-TI is a low-voltage adjustable precision 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%. The device supports a maximum cathode current of 15 mA and has a maximum reference input voltage of 35 V. It functions reliably across a temperature range of -40°C to +85°C with a temperature coefficient of 138 ppm/°C. Packaged in SOT-23-5, it serves as a precise voltage regulation component for low-power applications.

Voltage Reference Feature Summary

• Provides adjustable precision voltage regulation via a two-terminal shunt configuration
• Ensures high stability with low temperature coefficient characteristics
• Supports rail-to-rail operation for low-voltage system integration

Voltage Reference Applications

• Portable battery-powered equipment requiring stable reference voltages
• Microcontroller power supply monitoring circuits
• Low-dropout regulator feedback networks

Voltage Reference Procurement Notes

Verify the specific suffix 'TI' against official Texas Instruments documentation to confirm manufacturing origin and compliance status. Ensure the part number matches the exact package type and accuracy grade required for your design. Cross-reference with the official datasheet for any recent product change notices or end-of-life declarations before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable shunt reference with 1% initial accuracy is required. It is suitable for designs needing operation down to 2.5 V supply voltages. Consider the SOT-23-5 package constraints and thermal performance limits when integrating into compact PCB layouts compared to higher precision or wider operating temperature variants.

Voltage Reference Part Context

This component belongs to the LMV431 family of low-voltage adjustable shunt regulators. It is functionally compatible with the Zener diode but offers superior dynamic impedance and temperature stability. The LMV431 series is widely used in industrial and consumer electronics where precise voltage referencing is critical for analog-to-digital conversion and power management loops.

Voltage Reference Replacement Considerations

Direct substitutes include LMV431ACM5/NOPB. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
