AS431BRTR-E1

Overview

The AS431BRTR-E1 is an adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides a programmable output voltage ranging from 2.5V to 36V with a guaranteed initial accuracy of 1.0%. The device operates within a cathode current range of 1mA to 100mA and features a typical temperature coefficient of 20PPM/°C. It is housed in a SOT-89 surface-mount package and supports an ambient operating temperature range from -40°C to +125°C.

Feature Summary

Programmable precise output voltage spanning from 2.5V to 36V
High stability performance under capacitive load conditions
Low equivalent full-range temperature deviation for thermal consistency

Applications

Switching power supply regulation
Charger circuit design
Voltage adapter implementation
Graphic card power management
Precision voltage reference generation

Procurement Notes

Verify the specific ordering suffix E1 against the manufacturer's official documentation to confirm compliance with lead-free requirements. Ensure that the selected component matches the required voltage tolerance specification of 1.0% for the intended application. Cross-reference the package type and marking information to prevent substitution errors during assembly.

Selection Notes

Select this component when a low-cost, high-stability shunt regulator is required for applications needing adjustable voltage references up to 36V. Consider the SOT-89 package dimensions and thermal resistance characteristics for proper heat dissipation. Evaluate the minimum cathode current requirement of 1mA to ensure stable regulation across the entire operating temperature range.

Part Context

This part belongs to the AS431 series of three-terminal adjustable shunt regulators designed as alternatives to Zener diodes. The series offers various packages including TO92, SOT23, SOT25, and SOT89. The BRTR-E1 designation specifically indicates the 1.0% tolerance variant packaged in SOT-89 with tape-and-reel delivery format.
