SPX2431M-L/TR

Overview

The SPX2431M-L/TR is a precision adjustable shunt voltage reference manufactured by MaxLinear, Inc. It operates within an output voltage range of 2.5 V to 20 V and supports a maximum shunt current of 100 mA. The device is housed in a compact 3-pin SOT-23 package and is supplied in tape and reel format for automated assembly.

Feature Summary

• Provides stable and precise voltage regulation suitable for demanding analog circuit applications
• Features an adjustable output configuration allowing flexible integration into various power management designs

Applications

• Precision voltage reference sources for data acquisition systems
• Reference inputs for analog-to-digital converters (ADCs)
• Voltage monitoring circuits requiring high stability

Procurement Notes

Verify the manufacturer designation on the component marking, as historical records indicate production by Exar Corporation prior to its acquisition by MaxLinear. Confirm that the specific lot corresponds to the MaxLinear branding to ensure accurate traceability and compliance with current quality standards.

Selection Notes

Select this component when a low-cost, adjustable shunt reference is required in a small surface-mount footprint. Ensure the application design accommodates the 100 mA maximum current capability and verify that the operating temperature range aligns with the specified environmental conditions for the target deployment.

Part Context

This part belongs to the SPX2431 series of shunt regulators, which are direct replacements for industry-standard Zener-based references. The series offers improved accuracy and lower noise characteristics compared to traditional discrete solutions, making it a common choice for cost-sensitive consumer electronics and industrial instrumentation.
