Frequently Asked Questions
What is the output voltage range of the TL431ACDBZR?
The TL431ACDBZR supports an adjustable output voltage range from 2.5V (reference voltage) up to 36V, with a maximum output current of 100mA. The 1% accuracy ensures precise regulation across the full range, making it suitable for demanding power supply applications.
What package does the TL431ACDBZR use and what are its dimensions?
The TL431ACDBZR comes in the SOT-23-3 (DBZ) surface-mount package, which is a compact 3-pin package ideal for space-constrained PCB designs. It is Pbfree and REACH compliant, meeting modern environmental standards for electronic components.
What are the typical applications of the TL431ACDBZR?
The TL431ACDBZR is commonly used in switching power supply feedback loops, voltage reference circuits, battery charger management, overvoltage and undervoltage protection, and precision current limiting circuits. Its adjustable 1% accuracy shunt regulation makes it a standard component in consumer electronics, industrial equipment, and telecom power systems.
How does the TL431ACDBZR compare to the standard TL431?
The TL431ACDBZR offers tighter 1% initial accuracy compared to the standard TL431's 2% tolerance, making it suitable for precision applications. The 'A' suffix indicates improved accuracy, while the 'DBZ' suffix denotes the compact SOT-23-3 package. It is pin-compatible and can directly replace standard TL431 variants in most designs.
