AZ431LBNTR-E1

Overview

The AZ431LBNTR-E1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within an output voltage range of 1.24 V to 18 V and features an initial accuracy of 0.5%. The device has a maximum cathode current of 100 mA and a temperature coefficient of 20 PPM/°C. It functions between -40°C and +125°C, housed in an SOT-23-3 surface-mount package.

Feature Summary

• Adjustable precise output voltage programmable via two external resistors
• Guaranteed thermal stability across the full operating temperature range
• Low temperature deviation for consistent reference performance
• High stability under capacitive load conditions

Applications

• Switching power supply regulation
• Battery charger circuits
• Motherboard voltage references
• General-purpose adjustable regulators

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before integration. Ensure storage conditions meet moisture sensitivity level standards to prevent package damage during soldering processes.

Selection Notes

Select this component when low-voltage precision referencing is required in compact designs. The SOT-23-3 package suits space-constrained applications. Verify that the 100 mA cathode current capability meets circuit sink requirements. Consider the 0.5% initial accuracy for tight tolerance needs compared to standard variants.

Part Context

This part belongs to the AZ431L series, designed as a low-voltage alternative to traditional Zener diodes. It offers superior stability and lower impedance characteristics. The series includes various packages like TO-92 and SOT-89, with the L suffix typically denoting the 1.24V minimum reference point.
