LX6431AILP

Overview

The LX6431AILP is a precision shunt voltage reference integrated circuit manufactured by Microsemi Corporation. It features an adjustable output voltage range spanning from 2.5 V to 36 V, allowing for flexible configuration in various analog circuits. The device provides an output current capability of 100 mA and maintains a tight initial tolerance of ±1%. Packaged in a TO-92-3 (TO-226-3) housing, this single-channel component serves as a stable voltage reference source for applications requiring precise potential regulation.

Feature Summary

• Adjustable output voltage capability across a wide operational range
• High precision with specified initial tolerance accuracy
• Shunt regulator topology for stable voltage referencing

Applications

• Precision analog signal conditioning circuits
• Battery-powered instrumentation requiring stable references
• Data acquisition systems needing accurate voltage benchmarks

Procurement Notes

Verify the specific suffix 'AILP' corresponds to the required package type and tolerance grade. Confirm that the manufacturer designation aligns with current Microchip Technology holdings following the Microsemi acquisition. Ensure the ordering information matches the exact electrical specifications required for the design, particularly the adjustable voltage range and current limits.

Selection Notes

Select this component when a programmable shunt reference is required within a TO-92 form factor. Consider the 100 mA output current limit against the load requirements. Evaluate the ±1% tolerance against system accuracy needs. Compare against fixed-reference alternatives if the voltage requirement does not necessitate adjustability up to 36 V.

Part Context

This part belongs to the LX6431 series of precision programmable voltage references. The series offers various package options and tolerance grades to suit different design constraints. As a shunt reference, it operates by sinking current to maintain a constant voltage drop, differing from series regulators that pass current to the load.

Replacement Considerations

Check for direct pin-compatible substitutes within the LX6431 family that may offer different tolerances or packaging. Verify functional equivalence regarding the adjustable voltage range and maximum output current before substituting.
