TS2431EILT

Overview

The TS2431EILT is an adjustable shunt voltage reference manufactured by STMicroelectronics, housed in a SOT-23-3 surface-mount package. It provides an output voltage range from 2.5 V to 24 V with an initial accuracy of ±2%. The device operates within a temperature range of -40°C to +105°C and features a temperature coefficient of 100 ppm/°C. It supports a cathode current of 1 mA minimum and up to 100 mA maximum, with a maximum input voltage of 25 V.

Feature Summary

• Adjustable shunt voltage reference architecture
• Guaranteed temperature stability across the full operating range
• Compact SOT-23-3 surface-mount packaging

Applications

• Portable equipment power management
• Battery-powered systems
• General-purpose voltage regulation

Procurement Notes

Verify the specific suffix 'E' against the official datasheet to confirm environmental compliance or grade variations. Ensure the SOT-23-3 footprint matches the PCB design. Confirm RoHS status and lead-free specifications with the supplier prior to ordering.

Selection Notes

Select this component for applications requiring a low-cost, adjustable reference in space-constrained designs. The wide output voltage range allows flexibility in setting reference levels without external resistors if fixed options are insufficient. Consider the 100 ppm/°C drift for precision requirements.

Part Context

This part belongs to the TS2431 family of adjustable shunt references. It serves as a cost-effective alternative to series regulators in low-power applications where a stable reference voltage is needed for ADCs, DACs, or comparator thresholds.

Replacement Considerations

Check for direct pin-compatible substitutes such as other adjustable shunt references in SOT-23 packages. Verify that replacement parts meet the same 24 V max output and 100 mA current capabilities.
