LMV431CM5X/NOPB

Voltage Reference Overview

The LMV431CM5X/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 features an initial accuracy of 1.5%. The device supports a maximum shunt current of 15 mA and withstands a maximum series 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 a surface-mount SOT-23-5 format, it serves as a precision reference for power management applications.

Voltage Reference Feature Summary

• Provides adjustable voltage referencing capability within a low-voltage operational range
• Delivers stable performance with specified initial accuracy and temperature stability
• Designed for surface-mount integration in compact electronic circuits

Voltage Reference Applications

• Battery-powered equipment requiring precise voltage monitoring
• Portable devices utilizing low-voltage power supplies
• General-purpose voltage reference circuits in consumer electronics

Voltage Reference Procurement Notes

Verify the specific suffix 'X' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the required SOT-23-5 footprint and electrical tolerances for your design. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and RoHS compliance details before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a low-voltage adjustable reference is needed with moderate accuracy requirements. It is suitable for designs where space is limited due to its small SOT-23-5 package. Consider the 15 mA current limit and 1.5% initial accuracy when designing feedback networks. Compare with higher-precision or higher-current alternatives if the application demands stricter tolerance or load capabilities.

Voltage Reference Part Context

This part belongs to the LMV431 family of low-voltage shunt regulators from Texas Instruments. It shares functional similarities with the LM431 but is optimized for lower supply voltages. The 'NOPB' suffix indicates lead-free construction and no post-production changes. It is distinct from the standard LMV431CM5, often differing in packaging configuration such as reel versus bulk.

Voltage Reference Replacement Considerations

LMV431CM5/NOPB is listed as a direct substitute for older LMV431CM5 variants.
