LMV431AIMF

Voltage Reference Overview

The LMV431AIMF/NOPB is a low-voltage shunt adjustable precision 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 has a temperature coefficient of 138 PPM/C, with a maximum series input voltage of 35 V and a maximum shunt current of 15 mA. It functions reliably across a temperature range from -40 C to +85 C. Packaged in a SOT-23-3 surface-mount format, it belongs to the LMV431A series under PMIC classification.

Voltage Reference Feature Summary

• Provides precise shunt regulation with adjustable output voltage capability
• Ensures stable performance through low temperature coefficient characteristics
• Supports high input voltage tolerance for flexible circuit integration

Voltage Reference Applications

• Precision voltage reference circuits
• Portable instrumentation systems
• Battery-powered equipment monitoring

Voltage Reference Procurement Notes

Verify the specific ordering suffix, such as NOPB, to confirm compliance with RoHS standards and lead-free manufacturing requirements. Ensure the package type matches the SOT-23-3 specification for proper PCB footprint alignment. Confirm that the selected variant meets the required initial accuracy and temperature coefficient specifications for the intended application environment before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a low-voltage, high-precision reference is needed in a compact surface-mount package. Consider the 1% initial accuracy and 138 PPM/C temperature coefficient against system stability requirements. Evaluate the 15 mA maximum shunt current limit to ensure adequate biasing for the reference node without exceeding device ratings during operation.

Voltage Reference Part Context

This part belongs to the LMV431A series of low-voltage shunt adjustable references. It serves as a modern alternative to traditional Zener diodes, offering superior accuracy and lower noise. The family includes various package options like SOT-23-3 and TO-92-3, catering to different assembly needs while maintaining consistent electrical performance characteristics across the series.

Voltage Reference Replacement Considerations

Direct substitutes include LMV431AIMFX/NOPB and LMV431AIZ/NOPB, which share identical electrical specifications but differ in packaging or reel configuration.
