SC431LI5SK-1TRT

Overview

The SC431LI5SK-1TRT is an adjustable shunt voltage reference manufactured by Semtech Corporation. It operates within a cathode current range of 100 µA to 100 mA and provides an adjustable output voltage from 1.24 V to 20 V. The device features an initial accuracy of 1% and functions across a temperature range of -40°C to +85°C. Packaged in a SOT-23-3 surface-mount format, it serves as a precision reference component for power management circuits.

Feature Summary

Adjustable output voltage capability via external resistors
Low dynamic output impedance for stable regulation
Trimmed bandgap design ensuring high accuracy
Thermal stability guaranteed over the operating temperature range

Applications

Linear regulators
Switching power supplies
Battery operated computers
Instrumentation systems

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official documentation to ensure compatibility with specific tolerance and packaging requirements. Confirm availability status as distribution channels may list obsolete or limited stock items. Cross-reference the part number with authorized Semtech distributors to validate authenticity and sourcing integrity before procurement.

Selection Notes

Select this component when a low-cost, adjustable shunt regulator with 1% initial accuracy is required. Ensure the application demands an output voltage between 1.24 V and 20 V and operates within the specified -40°C to +85°C temperature range. Verify that the circuit can support the minimum cathode current of 100 µA for proper regulation.

Part Context

This component belongs to the SC431 family of adjustable shunt regulators produced by Semtech. It is designed as a replacement for standard zener diodes and other similar references like TL431 variants. The LI5SK-1TRT designation indicates specific tolerance, package type, and tape-and-reel packaging for automated assembly processes.
