Introducing the AP431RA Voltage Reference from Diodes Incorporated

The AP431RA is a high-performance adjustable precision shunt regulator from Diodes Incorporated. This product is designed to provide a reliable and stable reference voltage for various applications, including power supplies, battery chargers, and voltage monitoring systems.

Featuring a three-terminal adjustable shunt regulator, the AP431RA offers an output voltage range that can be set to any value between 2.5V and 36V with two external resistors. This flexibility makes it an ideal choice for designers who require a precise voltage reference but also need the versatility to adjust the output according to their specific needs.

The AP431RA boasts a low dynamic output impedance of 0.2 ohms, ensuring stable voltage regulation even under changing load conditions. Its low output noise and excellent temperature stability (with a typical temperature coefficient of only 50 ppm/°C) make it a reliable choice for precision applications.

With a typical output voltage accuracy of 1% and the ability to source up to 100mA of output current, the AP431RA is suitable for high-accuracy and high-power applications. It also offers excellent transient response characteristics, which is crucial for maintaining voltage stability in the presence of sudden load changes.

Safety and reliability are key concerns in electronic design, and the AP431RA addresses these with built-in over-temperature and over-current protection features. This ensures that the device remains safe and operational even under extreme conditions.

The AP431RA is available in a variety of packages, including the small SOT-23, which is perfect for space-constrained applications. Its lead-free and RoHS compliant design also makes it an environmentally friendly choice for modern electronic systems.

In conclusion, the AP431RA from Diodes Incorporated is a versatile, accurate, and robust voltage reference solution that meets the needs of a wide range of electronic applications. Its adjustable output, high accuracy, and strong protection features make it a go-to component for designers looking to enhance the performance and reliability of their power management systems.
