The Texas Instruments TL431BQDBVR is a three-terminal adjustable shunt regulator designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between approximately 2.5V (Vref) and 36V using two external resistors, making it a versatile component for on-board regulation and adjustable power supplies.
Key electrical characteristics include a reference voltage tolerance of 0.5% at 25°C (B grade) and a typical output impedance of 0.2Ω. The device supports a sink current capability ranging from 1mA to 100mA and operates efficiently from -40°C to 125°C.
Packaged in a compact SOT-23 (DBV) 5-pin surface-mount package, the TL431BQDBVR is suitable for applications requiring space efficiency. It is supplied on tape and reel with a standard package quantity of 3,000 units.
This shunt regulator serves as an excellent replacement for Zener diodes in many applications due to its sharp turn-on characteristic and programmable voltage output.
