The Texas Instruments TL431CDBZT is a three-terminal adjustable shunt regulator designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors, making it a versatile component for power management applications.
Key electrical characteristics include reference voltage tolerances of 0.5% (B grade), 1% (A grade), and 2% (Standard grade) at 25°C. The device operates from -40°C to 125°C and features a typical output impedance of 0.2Ω. It supports a sink current capability ranging from 1mA to 100mA.
This shunt regulator is housed in a SOT-23 surface-mount package, suitable for automated assembly processes. The standard package quantity is 3000 pieces on tape and reel.
Applications for the TL431CDBZT include on-board regulation, adjustable power supplies, and as a replacement for Zener diodes where improved performance and stability are required.
