LMV431ACZ/NOPB

Voltage Reference Overview

The LMV431ACZ/NOPB 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 shunt current of 15 mA with a maximum series input voltage of 35 V. It exhibits a temperature coefficient of 138 ppm/°C and functions reliably between -40°C and +85°C. Housed in a TO-92-3 through-hole package, this component belongs to the LMV431A series.

Voltage Reference Feature Summary

• Provides adjustable precision voltage referencing with a minimum reference voltage of 1.24 V
• Delivers high initial accuracy for stable reference performance across operating conditions
• Supports low-voltage operation suitable for battery-powered and portable applications

Voltage Reference Applications

• Battery-operated equipment requiring precise voltage monitoring
• Portable instruments needing compact adjustable references
• Power supply circuits utilizing shunt regulation topologies

Voltage Reference Procurement Notes

Verify that the ordering suffix matches the required package and temperature grade. Confirm RoHS compliance status as indicated in official documentation. Ensure the manufacturer part number corresponds exactly to the LMV431ACZ/NOPB designation to avoid functional mismatches due to variant differences.

Voltage Reference Selection Notes

Select this component when low-voltage operation and tight initial accuracy are required. The TO-92-3 package suits through-hole designs where space allows. Compare against higher-current alternatives if load requirements exceed 15 mA. Consider temperature coefficient specifications for environments with significant thermal variations.

Voltage Reference Part Context

This device is part of the LMV431 family of low-voltage adjustable shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior accuracy and lower temperature drift. The LMV431ACZ/NOPB specifically denotes the 1% accuracy variant in a through-hole package, distinguishing it from surface-mount or different tolerance versions within the same product line.

Voltage Reference Replacement Considerations

LMV431IZ/NOPB offers similar functionality but may differ in specific manufacturing lot characteristics. LMV431AIMF/NOPB provides the same electrical performance in a surface-mount SOT-23 package. Verify pinout compatibility and package dimensions before substituting.
