SC431LCSK-.5TRT.P2

Overview

The SC431LCSK-.5TRT.P2 is a shunt adjustable voltage reference manufactured by Semtech. It operates within an output voltage range of 1.24 V to 16 V and features an initial accuracy tolerance of ±0.5%. The device supports a cathode current range from 100 µA to 100 mA. It is housed in a surface-mount SOT-23-3 package and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Adjustable shunt regulation with wide output voltage capability
• High precision initial accuracy for stable reference performance
• Compact surface-mount packaging for space-constrained designs

Applications

• Precision voltage reference circuits
• Portable battery-powered equipment
• Industrial control systems

Procurement Notes

This component is officially classified as obsolete or end-of-life by the manufacturer. Verification of availability requires checking distributor channels for remaining stock or surplus inventory, as standard production supply is discontinued. Confirm specific lot dates and authenticity through authorized suppliers before procurement.

Selection Notes

Select this part when a compact, high-accuracy adjustable reference is required for low-power applications. Ensure the design accommodates the SOT-23-3 footprint and operates within the specified 0°C to +70°C temperature range. Verify that the 100 mA maximum cathode current meets the circuit's load requirements.

Part Context

Part of the SC431LC series, which offers various accuracy grades and package options. This specific variant provides a balance of precision and size, suitable for replacing legacy references in modern portable and industrial electronics where board space is limited.

Replacement Considerations

Verify pinout compatibility with direct replacements. Consider alternative shunt references from Semtech or other manufacturers if new design inclusion is required due to obsolescence.
