SC431LISK-1TRT

Overview

The SC431LISK-1TRT 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 20 V with an initial accuracy of 1%. The device operates with a cathode current ranging from 100 µA to 100 mA and functions within a temperature range of -40°C to +85°C. It lacks a shutdown feature and is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

Adjustable shunt regulation architecture for precise voltage referencing
High initial accuracy of 1% across the operating range
Wide output voltage capability from 1.24 V to 20 V
Robust operational current range supporting low to high load conditions

Applications

Precision power supply feedback loops
Portable equipment voltage monitoring
Battery management system references
Industrial control circuit regulation

Procurement Notes

Verify component obsolescence status prior to design finalization, as the part is listed as obsolete. Confirm availability through authorized distributors or secondary market channels due to restricted supply conditions. Ensure the selected packaging format (reel, cut tape, or MouseReel) aligns with manufacturing assembly requirements. Validate RoHS compliance documentation against specific regional regulatory standards before procurement execution.

Selection Notes

Select this component when a compact, adjustable shunt reference is required for space-constrained designs. The SOT-23-3 package offers a small footprint suitable for dense PCB layouts. Consider the 1% initial accuracy and wide current range for applications demanding stable performance without complex external compensation networks. Evaluate thermal constraints given the specified operating temperature limits.

Part Context

This device belongs to the SC431LISK series of adjustable shunt regulators. It serves as a critical component in power management integrated circuits, providing stable reference voltages for various analog and digital systems. The series is designed for general-purpose voltage regulation tasks where size and cost efficiency are prioritized alongside moderate precision requirements.
