Introducing the ZTL431BQFTA from Diodes Incorporated

The ZTL431BQFTA is a precision low-power shunt regulator that offers an excellent solution for voltage regulation needs in a wide range of applications. Manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality semiconductor products, this device is designed to maintain high stability and accuracy over a broad range of operating conditions.

With an output voltage range that can be set to any value between V<sub>REF (approximately 2.5V) and 20V with two external resistors, the ZTL431BQFTA provides exceptional flexibility. This makes it ideal for use in adjustable power supplies, isolated feedback circuits, and precision voltage references in consumer, industrial, and automotive applications.

The ZTL431BQFTA features a typical temperature coefficient of only 50 ppm/°C, ensuring a consistent performance across a temperature range of -40°C to +125°C. This precision is critical in applications requiring a stable voltage reference under varying environmental conditions. Additionally, the device boasts a low output noise, which is essential for sensitive electronic equipment where noise can significantly impact performance.

This shunt regulator comes in a small SOT-23 package, making it suitable for space-constrained applications. Despite its compact size, it offers a dynamic impedance of 0.22 ohms, providing a stable voltage reference and regulation with minimal power loss.
