SC431LCSK-2TR

Overview

The SC431LCSK-2TR is an adjustable shunt voltage reference manufactured by Semtech. It provides a stable output voltage ranging from 1.24V to 16V with an initial accuracy of ±2%. The device operates within a cathode current range of 100µA to 100mA and supports surface mount installation in a SOT-23-3 package. It functions without a shutdown mode and maintains performance across a commercial temperature range of 0°C to 70°C.

Feature Summary

Adjustable shunt regulation architecture
High precision initial accuracy
Wide operating current range
Compact surface-mount packaging

Applications

Portable electronic equipment power supplies
Battery-powered instrumentation
General-purpose voltage references

Procurement Notes

Verify component status as the SC431LCSK-2TR is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets, noting potential supply restrictions. Ensure compatibility with existing designs before procurement due to end-of-life status.

Selection Notes

Select this component for applications requiring a low-cost, adjustable reference in space-constrained designs. The SOT-23-3 package suits small footprints. Verify that the ±2% accuracy meets system requirements and that the 100mA maximum cathode current aligns with load demands. Consider thermal management within the specified 0°C to 70°C range.

Part Context

This part belongs to the SC431LC series of adjustable shunt regulators. It shares functional similarities with industry-standard TL431 devices but is produced by Semtech. The series offers various tolerance options and packaging configurations for different precision and form-factor needs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, cross-reference with equivalent adjustable shunt references in SOT-23-3 packages may be necessary.
