Overview
The AN431AN-ATRE1 is a three-terminal adjustable precision shunt regulator from Diodes Incorporated, housed in an SOT-23 package. It provides a programmable output voltage ranging from 2.5V to 36V with a reference voltage tolerance of ±0.5%. The device operates within a cathode current range of 1mA to 100mA and supports a maximum cathode voltage of 36V. It features a typical temperature coefficient of 20ppm/°C and maintains stability across an ambient temperature range of -40°C to +125°C.
Feature Summary
- Programmable precise output voltage capability between the internal reference and maximum cathode voltage limits
- Guaranteed thermal stability over the full operating temperature range with low temperature deviation
- Low dynamic output impedance ensuring stable performance under varying load conditions
Applications
- Charger circuits
- Voltage adapters
- Switching power supplies
- Graphic cards
- Precision voltage references
Procurement Notes
Verify the specific suffix codes against official documentation to confirm package type, tolerance class, and environmental compliance status. Ensure that the ordering information matches the required electrical characteristics for your design. Cross-reference datasheet revisions to confirm pin assignments and absolute maximum ratings remain consistent with your system requirements before finalizing procurement.
Selection Notes
Select this component when a compact, adjustable shunt regulator is needed for space-constrained designs. The SOT-23 package suits surface-mount applications requiring minimal board area. Consider the 0.5% initial accuracy and wide operating temperature range for systems demanding high precision and reliability under varying thermal conditions without requiring external trimming components.
Part Context
This part belongs to the AN431 series of adjustable precision shunt regulators manufactured by Diodes Incorporated. The series serves as a direct replacement for Zener diodes in various power management applications. The AN431 variant specifically supports up to 36V operation, distinguishing it from lower-voltage counterparts within the broader product family.
Replacement Considerations
Compatible substitutes include AZ431AN-ATRE1 and AS431HMANTR-G1. Verify pinout compatibility and ensure the alternative part meets the required voltage tolerance and operating temperature specifications for your specific application environment.
