SPX431LAM-L/TR

Overview

The SPX431LAM-L/TR is a precision adjustable shunt regulator manufactured by Sipex, classified under PMIC voltage references. It operates in an SOT-23-3 package with surface-mount installation. The device provides an output voltage range of 2.5 V to 20 V, featuring an initial accuracy of 0.5% and a temperature coefficient of 30 PPM/°C. Maximum input voltage is 2.52 V, with a maximum shunt current of 100 mA and minimum operating current of 1 mA. It functions within a temperature range of 0°C to +105°C, drawing a typical supply current of 10 mA.

Feature Summary

Precision adjustable shunt regulation capability
Wide output voltage adjustability via external resistors
High initial accuracy for stable reference performance

Applications

Voltage reference sources in measurement circuits
Adjustable power supply feedback loops
Comparator reference voltage generation

Procurement Notes

Verify component authenticity due to discontinued status and multiple manufacturer origins including MaxLinear and Sipex. Confirm RoHS compliance details as listed varies by source. Check moisture sensitivity levels before soldering. Ensure package type matches design requirements as variants exist. Validate datasheet version against specific production batch for accurate electrical characteristics.

Selection Notes

Select this component when a low-cost, high-accuracy shunt regulator is required for fixed or adjustable reference applications. Consider the SOT-23-3 footprint constraints and thermal limits. Verify that the 100 mA maximum shunt current meets load requirements. Compare against newer MaxLinear equivalents if long-term availability is critical.

Part Context

This part belongs to the SPX431L series of precision shunt regulators. Originally associated with Sipex, later documentation links it to MaxLinear. It serves as a two-terminal voltage reference alternative to bandgap sources. The family includes various package options like SOT-89-3 and SOIC-8 variants.
