Introducing the AZ431LBZ-E1 from Diodes Incorporated

The AZ431LBZ-E1 is a precision programmable shunt regulator from Diodes Incorporated, designed to offer a solution for voltage reference and regulation requirements across a broad range of applications. This component is a three-terminal adjustable regulator with guaranteed thermal stability over a full operation range.

Constructed with advanced silicon technology, the AZ431LBZ-E1 provides sharp turn-on characteristics, low dynamic output impedance, and a stable hysteresis characteristic, making it a reliable choice for precision regulation tasks. Its programmable output voltage can be set to any value between Vref (approximately 2.5V) and 36V with two external resistors. This feature allows designers the flexibility to tailor the output to their specific needs without having to switch to different reference components.

The device boasts a low equivalent full-range temperature coefficient with a typical value of 50ppm/°C, which ensures a consistent performance over its operating temperature range of -40°C to +85°C. This temperature stability, combined with a fast turn-on response and a sharp knee on the V-I characteristics curve, makes the AZ431LBZ-E1 an excellent choice for high-performance applications requiring a stable reference voltage.

Applications for the AZ431LBZ-E1 are diverse and include use in switch-mode power supplies, battery chargers, computer monitors, and appliances where precise voltage control is critical. It's also commonly used in power management circuits, precision voltage regulation schemes, and as a replacement for Zener diodes in many applications where improved output voltage precision is necessary.

The AZ431LBZ-E1 is offered in a standard TO-92 package, ensuring compatibility with a wide range of PCB layouts and easy integration into existing designs. Its lead-free and RoHS-compliant construction aligns with modern environmental standards, addressing the needs of eco-conscious product designs.

Overall, the AZ431LBZ-E1 shunt regulator from Diodes Incorporated is a versatile and reliable component that provides high-precision voltage regulation, making it an essential part of any power management solution.
