Adjustable Shunt Voltage Reference IC for Precision Regulation and Power Control Applications

The TL431BQDBZR is an adjustable shunt voltage reference IC designed to deliver accurate and stable voltage regulation across a wide range of applications. Acting as a programmable precision reference, it allows the output voltage to be set anywhere between approximately 2.5V and 36V using just two external resistors. This flexibility makes it a practical alternative to fixed Zener diodes in modern electronic designs where tighter tolerance and sharper regulation are required.

With a typical output impedance of just 0.2ohm and a fast, sharp turn-on characteristic, the TL431BQDBZR ensures excellent dynamic response in feedback and control loops. It supports cathode currents up to 100mA, making it suitable for on-board regulation, adjustable power supplies, SMPS feedback circuits, battery chargers, and voltage monitoring systems. The compact SOT-23-3 package further enables easy integration into space-constrained PCBs used in industrial, consumer, and automotive electronics.
