AZ431LAKTR-G1

Overview

The AZ431LAKTR-G1 is a low-voltage adjustable precision shunt regulator from the AZ431L series by Diodes Incorporated. It operates within an output voltage range of 1.24V to 18V, set via two external resistors. The device features a 0.5% initial accuracy and a typical temperature coefficient of 20PPM/°C. It supports a cathode current range from 0.1mA to 100mA with a maximum input voltage of 20V. Packaged in SOT-25 (SOT23-5) format, it functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

Provides wide programmable precise output voltage ranging from 1.24V to 18V using external resistors
Ensures high stability under capacitive loads with sharp turn-on characteristics
Delivers low dynamic output resistance and low output noise for clean reference signals
Complies with RoHS 3 standards and utilizes halogen-free green molding compound

Applications

Graphic cards
PC motherboards
Voltage adapters
Switching power supplies
Chargers

Procurement Notes

Verify that the specific order matches the AZ431LAKTR-G1 designation to ensure the correct 0.5% tolerance and SOT-25 package configuration. Confirm compliance requirements against the latest datasheet revision DS36801 Rev. 5-2. Check for any applicable automotive qualification needs, as standard parts are not AEC-Q100 qualified unless specified. Ensure design reviews account for the NRND status of similar legacy packages if migrating designs.

Selection Notes

Select this component when a low-voltage adjustable reference with tight 0.5% initial accuracy is required. The SOT-25 package offers a five-pin configuration suitable for compact surface-mount layouts. Consider the 20PPM/°C temperature coefficient for applications demanding thermal stability. Verify that the load capacitance remains within stable operating limits defined in the performance characteristics to prevent oscillation.

Part Context

This part belongs to the AZ431L series of low-voltage adjustable precision shunt regulators. The series includes variants with different tolerances (0.5% and 1.0%) and packages such as TO92, SOT23, and SOT89. The 'A' suffix indicates 0.5% voltage tolerance, while 'K' denotes the SOT-25 package. The 'G1' suffix confirms RoHS compliance and green material composition.
