Introducing the AP431WL from Diodes Incorporated

The AP431WL is a high-performance adjustable precision shunt regulator designed by Diodes Incorporated, a leading manufacturer and supplier of high-quality semiconductor products. With its precise voltage reference and low output noise, this component is ideal for a variety of applications, including power supplies, battery chargers, and voltage monitoring systems.

Featuring a three-terminal adjustable shunt regulator similar to the TL431 but with enhanced stability and lower voltage operation, the AP431WL allows for easy adjustable output levels. It provides a reference voltage range from 2.5V to 36V, with an impressive accuracy of 1.5% over the entire temperature range of -40°C to 85°C.

The AP431WL's low dynamic output impedance, which is a mere 0.2 ohms, coupled with a sink current capability ranging from 1mA to 100mA, makes it an excellent choice for precision voltage regulation tasks. This flexibility ensures that it can be tailored to a wide range of design requirements, making it a versatile component in any electronic engineer's toolkit.

Another key feature of the AP431WL is its low quiescent current, which contributes to energy efficiency in the final application. This is particularly important for battery-operated devices where power conservation is critical. The device also offers excellent thermal stability, ensuring consistent performance across its full operating temperature range.

For ease of integration into various circuit designs, the AP431WL is offered in multiple package options including the SOT-23, which is suitable for space-constrained applications. Its robust design also ensures that it is capable of withstanding harsh operating conditions, making it reliable for industrial and automotive applications as well.

In summary, the AP431WL from Diodes Incorporated stands out as a highly reliable and precise adjustable shunt regulator. Its combination of low voltage operation, high accuracy, and versatility makes it an excellent choice for designers looking to improve the performance and efficiency of their power management systems.
