Voltage Reference Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 30 V for flexible circuit design
• Low-voltage operation optimized for battery-powered applications with minimal power consumption
• High precision performance characterized by 1% initial accuracy and stable thermal behavior

Voltage Reference Applications

• Portable equipment requiring precise low-voltage regulation
• Battery-operated systems needing efficient power management
• General-purpose voltage reference circuits in industrial instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix 'M5X' confirms the SOT-23-5 surface-mount package configuration. Ensure the '/NOPB' designation indicates lead-free construction compliant with RoHS standards. Confirm the 'A' grade specifies the 1% initial accuracy requirement rather than standard tolerance variants. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate active status and availability.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage shunt regulation. The SOT-23-5 package offers space efficiency compared to larger through-hole alternatives. Choose this variant over standard LMV431 models if the 1% accuracy grade and 15 mA current capability are necessary constraints. Consider the 138 PPM/°C temperature coefficient for thermal stability requirements in the target application environment.

Voltage Reference Part Context

This device belongs to the LMV431A family of low-voltage adjustable shunt references. It serves as a high-precision alternative to traditional Zener diodes, offering superior temperature stability and lower dynamic impedance. The component integrates a bandgap reference and error amplifier within a small footprint, enabling direct replacement in existing designs requiring improved accuracy and reduced size.
