LMV431CM5/NOPB

Voltage Reference Overview

The LMV431CM5/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 supports a maximum shunt current of 15 mA. The device features an initial accuracy of 1.5% and a temperature coefficient of 138 ppm/°C. It is housed in a 5-pin SOT-23 package designed for surface mount installation. The component functions with a maximum series reference input voltage of 35 V and operates reliably across a temperature range from -40°C to +85°C.

Voltage Reference Feature Summary

• Provides precise adjustable voltage referencing through a two-terminal shunt configuration suitable for low-voltage applications.
• Delivers stable performance with specified initial accuracy and temperature coefficient characteristics over the operating range.
• Designed for compact surface-mount integration using a standard five-pin SOT-23 package format.

Voltage Reference Applications

• Portable battery-powered equipment requiring precise voltage monitoring
• Power supply circuits utilizing adjustable regulation topologies
• General-purpose voltage reference sources in consumer electronics

Voltage Reference Procurement Notes

Verify the specific suffix designation to confirm the presence of lead-free plating and environmental compliance standards. Confirm the package type matches the intended PCB footprint requirements. Ensure the operating temperature range aligns with the final application environment. Check for any process change notifications that may affect long-term availability or material composition.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable shunt reference is required for space-constrained designs. The 1.5% initial accuracy is sufficient for many general-purpose applications where tighter tolerances are not critical. Consider the 15 mA current limit when designing feedback networks to ensure adequate biasing without exceeding specifications.

Voltage Reference Part Context

This part belongs to the LMV431 family of low-voltage adjustable shunt references. It serves as a cost-effective alternative to higher-power devices like the LM431, offering lower current consumption and smaller packaging. The NOPB suffix indicates a lead-free and RoHS-compliant variant produced by Texas Instruments.

Voltage Reference Replacement Considerations

The LMV431CM5 is listed as obsolete with the LMV431CM5/NOPB identified as a direct replacement. Verify pinout compatibility and electrical parameter equivalence before substituting other adjustable shunt references from different manufacturers.
