Overview
The AZ431BZ-AE1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of 2.5V to 36V and features an initial accuracy of 0.8%. The device provides a typical temperature coefficient of 20PPM/°C and maintains stability under capacitive loads. It supports a sink current capacity from 1mA to 100mA with low output noise characteristics. The component is housed in a TO-92 package and is designed for operation across a wide ambient temperature range.
Feature Summary
- Adjustable precise output voltage programmable between the reference voltage and maximum cathode voltage
- High thermal stability guaranteed over the full operating temperature range
- Low equivalent full-range temperature coefficient ensuring minimal deviation
- Capable of sinking current from 1mA to 100mA with low dynamic output impedance
Applications
- Charger circuits
- Voltage adapters
- Switching power supplies
- Graphic cards
- Precision voltage references
Procurement Notes
Verify the specific ordering suffix to confirm the package type, voltage tolerance, and compliance status. Confirm the manufacturing status as active or end-of-life before finalizing procurement plans. Ensure the selected variant matches the required packaging format for the intended assembly process.
Selection Notes
Select this component when a stable, adjustable shunt regulator is required for power management applications. Consider the 0.8% initial accuracy and TO-92 through-hole package constraints. Evaluate the thermal resistance and power dissipation limits relative to the expected cathode current and ambient operating conditions.
Part Context
