LMV431ACM5/NOPB

Voltage Reference Overview

The LMV431ACM5/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 maintains an initial accuracy of 1%. The device supports a maximum cathode current of 15 mA with a minimum operating current of 100 µA. It features a temperature coefficient of 138 ppm/°C and withstands a maximum series VREF input voltage of 35 V. The component functions across a temperature range from -40°C to +85°C and is housed in a surface-mount SOT-23-5 package.

Voltage Reference Feature Summary

• Provides precise adjustable voltage referencing with 1% initial accuracy for stable circuit operation.
• Operates efficiently at low voltages starting from 1.24 V, suitable for battery-powered applications.
• Features a compact SOT-23-5 surface-mount footprint designed for space-constrained PCB layouts.

Voltage Reference Applications

• Portable consumer electronics requiring low-power voltage regulation
• Battery-operated devices needing precise reference levels

Voltage Reference Procurement Notes

Verify the specific suffix 'CM5' corresponds to the SOT-23-5 package configuration required for your design. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the exact electrical grade and packaging format specified in your bill of materials to avoid integration errors.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable shunt reference is needed for low-voltage systems. The 1% accuracy and 138 ppm/°C temperature coefficient suit general precision applications. Consider the SOT-23-5 package for surface-mount assembly. Evaluate if the 15 mA cathode current limit meets the load requirements compared to higher-current alternatives like the LM431 series.

Voltage Reference Part Context

This part belongs to the LMV431A family of low-voltage adjustable shunt references from Texas Instruments. It serves as a modern replacement for older discrete zener diode solutions, offering superior stability and lower noise. The LMV431 series is widely used in power management ICs and portable equipment where space and power efficiency are critical constraints.

Voltage Reference Replacement Considerations

Direct replacements include LMV431ACM5X/NOPB for tape-and-reel packaging. For non-NOPB versions, verify RoHS compatibility. Cross-reference with LMV431AIM5/NOPB if tighter tolerance is required, though pricing and availability may differ.
