Overview
The AZ431AN-BTRE1 is a three-terminal adjustable precision shunt regulator from the AZ431-B series by Diodes Incorporated. It provides a programmable output voltage ranging from 2.5V to 18V with an initial accuracy of ±0.4%. The device operates within a cathode voltage range up to 18V and supports a sink current capacity between 1mA and 100mA. It features a typical low temperature coefficient of 20ppm/°C and maintains thermal stability across an operating ambient temperature range of -40°C to +125°C.
Feature Summary
- Programmable precise output voltage setting capability
- Guaranteed thermal stability over full operation range
- Low equivalent full-range temperature coefficient
- High stability under capacitive load conditions
Applications
- Charger circuits
- Voltage adapters
- Switching power supplies
- Graphic cards
- Precision voltage references
Procurement Notes
Verify that the ordering suffix BTRE1 corresponds to the SOT-23 package, 0.4% tolerance, Tape & Reel packing, and RoHS compliant status as defined in the manufacturer's official documentation. Confirm the specific part marking EA4 matches the requested component variant before finalizing procurement orders.
Selection Notes
Select this component when a 20V maximum cathode voltage rating is required instead of the standard 36V AZ431-A series. Ensure the application utilizes external resistors to set the desired output voltage above the internal 2.5V reference. Verify that the load capacitance remains within the stability boundary conditions specified for the operating voltage.
Part Context
This component belongs to the AZ431-B family of adjustable precision shunt regulators. Unlike the AZ431-A series which supports voltages up to 36V, the AZ431-B series is rated for a maximum cathode voltage of 20V. It serves as a direct replacement for Zener diodes in applications requiring higher precision and lower temperature drift.
Replacement Considerations
