LMV431BCM5

Voltage Reference Overview

The LMV431BCM5 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 provides a maximum cathode current of 15 mA. The device features an initial accuracy of ±0.5% and utilizes a SOT-23-5 surface-mount package. It is designed for applications requiring precise voltage referencing in space-constrained environments.

Voltage Reference Feature Summary

• Adjustable output voltage capability from the internal 1.24 V reference
• High precision with ±0.5% initial accuracy tolerance
• Low-voltage operation suitable for battery-powered systems

Voltage Reference Applications

• Portable equipment voltage references
• Battery-operated instrumentation
• Power supply feedback loops

Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the standard LMV431BCM5 may not meet current environmental regulations; the LMV431BCM5/NOPB variant is recommended for lead-free requirements. Validate package integrity and pin configuration against the SOT-23-5 specification before integration.

Voltage Reference Selection Notes

Select this component when high accuracy is required in a compact form factor. Ensure the application voltage does not exceed the 30 V maximum limit. Consider the LMV431BCM5/NOPB if lead-free manufacturing processes are mandatory. Evaluate thermal performance within the specified operating temperature range during circuit design.

Voltage Reference Part Context

This device belongs to the LMV431 family of low-voltage shunt regulators. It serves as a cost-effective alternative to Zener diodes, offering superior stability and lower dynamic impedance. The component is widely used in analog signal conditioning and power management circuits where precise voltage control is essential.
