LMV431BIMF

Voltage Reference Overview

The LMV431BIMF 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 functions across a temperature range of -40°C to +85°C. Packaged in a SOT-23-3 surface-mount format, it utilizes negative feedback from the cathode to the adjust terminal for regulation.

Voltage Reference Feature Summary

• Low-voltage operation with adjustable reference starting at 1.24 V
• High initial accuracy of ±0.5% tolerance
• Negative feedback configuration from cathode to adjust terminal

Voltage Reference Applications

• Precision voltage references in low-voltage systems
• Adjustable shunt regulation circuits
• Battery-powered equipment requiring stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix 'BIMF' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the component matches the required SOT-23-3 package dimensions and lead finish specifications for your PCB design. Cross-reference the part number with the latest Texas Instruments documentation to validate RoHS compliance and operating temperature ranges before procurement.

Voltage Reference Selection Notes

Select this component when a low-voltage adjustable reference is required with tight initial tolerance. The 15 mA current capability suits applications where power consumption must be minimized compared to higher-current alternatives. The SOT-23-3 package allows for compact board layouts in space-constrained designs.

Voltage Reference Part Context

This device belongs to the LMV431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior stability and lower dynamic impedance. The family is designed for applications requiring precise voltage referencing in portable and battery-operated electronics.

Voltage Reference Replacement Considerations

Compatible substitutes include the LMV431AIZ/NOPB and LMV431BIMFX/NOPB. Verify that replacement parts maintain the same 1.24 V minimum reference voltage and SOT-23-3 package compatibility.
