The TL431BIDBZT 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 highly versatile for different applications.
Key electrical specifications include a typical reference voltage tolerance of 0.5% at 25°C and a typical output impedance of 0.2Ω. The device supports a sink current capability ranging from 1mA to 100mA. It operates effectively within an ambient temperature range of -40°C to 85°C.
Packaged in a SOT-23 (DBZ) case, the TL431BIDBZT is suitable for surface-mount designs. Its active output circuitry ensures a sharp turn-on characteristic, positioning it as an excellent alternative to Zener diodes in applications such as on-board regulation and adjustable power supplies.
