Diodes Incorporated AP431SRG-7 Adjustable Precision Shunt Regulator

The AP431SRG-7 from Diodes Incorporated is a versatile and high-performance adjustable precision shunt regulator designed to cater to a myriad of applications requiring voltage regulation. This three-terminal regulator is a superior alternative to zener diodes in many applications requiring an improvement in zener performance in terms of operation stability and output regulation.

The AP431SRG-7 offers a wide operating voltage range from 2.5V to 36V, making it suitable for diverse applications. It boasts a low dynamic output impedance of 0.2 ohms, ensuring stable voltage regulation even with varying load conditions. The reference voltage tolerance is impressive, with options of ±1%, ±2%, and ±0.5% at 25°C, which translates into consistent and reliable performance.

One of the key features of the AP431SRG-7 is its adjustability. Users can set the output voltage from Vref (the reference voltage) to 36V by incorporating two external resistors. This feature provides designers with the flexibility to tailor the output voltage to their specific requirements without the need for multiple different regulators.

The AP431SRG-7 is also characterized by its low quiescent current, which makes it an energy-efficient choice for battery-powered devices. The typical output noise voltage is minimal, ensuring a clean and stable voltage supply, which is critical for sensitive electronics and precision instrumentation.

For ease of integration into various designs, the AP431SRG-7 comes in an SOT-23 package, known for its compact footprint. This small package size is highly beneficial for space-constrained applications, allowing designers to maintain a small form factor without compromising on performance.

Overall, the AP431SRG-7 adjustable precision shunt regulator is a reliable and economical solution for voltage regulation needs. With its high accuracy, stability, and adjustability, it stands out as an excellent choice for power supplies, battery chargers, and voltage monitoring applications, among others.
