The TL431CDBZR from Texas Instruments 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 on-board regulation and adjustable power supplies.
Key electrical characteristics include a typical reference voltage tolerance of 0.5% at 25°C for the B grade, and a typical output impedance of 0.2Ω. The device supports a sink-current capability ranging from 1mA to 100mA. It operates within a temperature range of 0°C to 70°C.
Packaged in a SOT-23 surface-mount case, the TL431CDBZR is suitable for applications requiring compact designs. The standard package quantity is 3000 units on tape and reel. Its active output circuitry ensures a sharp turn-on characteristic, serving as an effective replacement for Zener diodes in many electronic circuits.
