LMV431BCM5X

Voltage Reference Overview

The LMV431BCM5X is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 30 V and features an initial accuracy of 0.5%. The device supports a maximum shunt current of 15 mA and has a maximum series reference input voltage of 35 V. It exhibits a temperature coefficient of 138 ppm/°C and functions reliably across a temperature range from -40°C to +85°C. The component is housed in a 5-pin SOT-23 package.

Voltage Reference Feature Summary

• Provides low-voltage adjustable precision regulation with a minimum reference voltage of 1.24 V
• Delivers high initial accuracy of 0.5% for stable reference performance
• Operates with a low maximum shunt current of 15 mA suitable for power-sensitive designs

Voltage Reference Applications

• Low-voltage battery-powered equipment requiring precise voltage references
• Portable instruments needing compact adjustable shunt regulators
• Power supply circuits utilizing the device as a reference element

Voltage Reference Procurement Notes

Verify the specific suffix configuration against official Texas Instruments documentation to ensure compatibility with required packaging and environmental standards. Confirm that the 0.5% accuracy grade meets design specifications, as variations exist within the family. Cross-reference the 5-pin SOT-23 footprint with PCB layout requirements before procurement.

Voltage Reference Selection Notes

Select this component when low-voltage operation below standard Zener thresholds is required alongside tight tolerance needs. The 0.5% accuracy distinguishes it from lower-grade variants like the LMV431ACM5X. Ensure the application current remains within the 15 mA limit and the operating voltage stays within the 30 V maximum range for optimal performance.

Voltage Reference Part Context

This part belongs to the LMV431 family of low-voltage adjustable precision shunt regulators. Unlike the higher-current LM431 series, the LMV431 is optimized for lower power consumption with a 15 mA maximum shunt current. The BCM5X designation indicates a specific thermal and mechanical variant within the SOT-23-5 package line offered by Texas Instruments.

Voltage Reference Replacement Considerations

LMV431BCM5X/NOPB is a confirmed direct substitute offering identical electrical characteristics and pinout compatibility.
