SC431LC5SK.25TR

Overview

The SC431LC5SK.25TR is an adjustable shunt voltage reference manufactured by Semtech, housed in a surface-mount SOT-23-5 package. It provides an output voltage range from 1.24 V to 20 V with an initial accuracy of ±0.25%. The device operates within a temperature range of 0°C to +70°C and supports a cathode current range of 100 µA to 100 mA.

Feature Summary

• Adjustable shunt regulation architecture for precise voltage control
• High initial accuracy of ±0.25% for stable reference performance
• Compact SOT-23-5 surface-mount footprint for space-constrained designs

Applications

• Precision analog circuit voltage references
• Portable electronic device power management
• Battery-powered instrumentation systems

Procurement Notes

This component is officially discontinued by the manufacturer as of August 25, 2026. Verify end-of-life status and availability through authorized distributors before design finalization. Ensure compliance with RoHS requirements and confirm package integrity upon receipt.

Selection Notes

Select this part for applications requiring high precision (±0.25%) in a small SOT-23-5 package. It is suitable for low-power designs given its minimum operating current of 100 µA. Consider the limited output voltage range up to 20 V when designing feedback networks.

Part Context

Part of the SC431LC5SK series, this component serves as a two-terminal voltage reference. It functions similarly to standard zener diodes but offers superior stability and adjustability. The series is designed for general-purpose voltage regulation tasks in consumer and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the product's discontinued status.
