SC431LCSK-1TRT.P2

Overview

The SC431LCSK-1TRT.P2 is an adjustable shunt voltage reference manufactured by Semtech, housed in a SOT-23-3 surface-mount package. It provides an output voltage range from 1.24 V to 16 V with an initial accuracy of ±0.5%. The device operates with a cathode current ranging from 100 µA to 100 mA and functions within a temperature range of 0°C to +70°C. It lacks a shutdown feature and is supplied in cut tape or reel packaging.

Feature Summary

• Provides precise adjustable shunt regulation with high initial accuracy
• Designed for low-voltage applications with wide output flexibility
• Compact three-terminal surface-mount construction

Applications

• Precision voltage references in portable electronics
• Adjustable power supply feedback networks
• Battery-powered instrumentation circuits

Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm package integrity and pin alignment upon receipt. Check RoHS compliance documentation against specific regional regulations. Validate electrical parameters using bench testing before integration into final designs due to end-of-life status.

Selection Notes

Select this component when ±0.5% initial accuracy is required in a compact SOT-23-3 footprint. Ensure the application voltage does not exceed 16 V and current requirements stay within the 100 µA to 100 mA range. Consider thermal management for operation up to 70°C. Evaluate alternative sources given the discontinued status.

Part Context

This device belongs to the SC431LCSK series of low-voltage shunt regulators. It shares functional similarities with standard TL431 architectures but offers tighter tolerance specifications. The series is designed for cost-sensitive applications requiring reliable voltage referencing in small form factors without external trimming components.
