SPX431LM1-L/TR

Overview

The SPX431LM1-L/TR is a precision adjustable shunt voltage reference manufactured by MaxLinear. It operates within an output voltage range of 2.5 V to 20 V and features an initial accuracy of 0.5%. The device has a temperature coefficient of 30 PPM/C and supports a maximum shunt current of 100 mA with a minimum operating current of 1 mA. It functions within a supply voltage range up to 20 V, with a series VREF input maximum of 2.52 V. The component operates between 0°C and +105°C, consumes 10 mA of working power supply current, and is housed in an SOT-89-3 surface-mount package.

Feature Summary

Provides stable reference voltage via adjustable shunt regulation mechanism
Ensures high precision with low initial tolerance and controlled temperature drift
Supports wide operating temperature range for industrial environments

Applications

Precision analog-to-digital converter (ADC) reference sources
Digital-to-analog converter (DAC) voltage references
Battery-powered equipment requiring stable bias voltages

Procurement Notes

Verify the specific suffix L/TR against official MaxLinear documentation to confirm packaging details such as reel or cut tape specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the procurement channel provides valid traceability for this discontinued or end-of-life component variant.

Selection Notes

Select this component when a compact SOT-89-3 footprint is required for adjustable shunt regulation. Consider the 0.5% initial accuracy and 30 PPM/C temperature coefficient for applications demanding moderate precision. Verify that the load current requirements fall within the 1 mA to 100 mA operational window defined by the datasheet.

Part Context

This part belongs to the SPX431L series of precision shunt voltage references. It serves as a semiconductor alternative to discrete zener diode circuits, offering superior stability and lower noise characteristics. The device integrates a bandgap reference core with an NPN transistor for shunt control.
