The TL431AIDBZTG4 from Texas Instruments is a three-terminal adjustable precision shunt regulator. This device is designed for applications requiring stable voltage references, offering an adjustable output voltage that can be set anywhere between its internal reference voltage (approximately 2.5V) and 36V using two external resistors. It features a typical output impedance of 0.2Ω and active output circuitry for a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in various circuits.
Key electrical specifications include a reference voltage tolerance of 0.5% at 25°C (B grade) and a sink current capability ranging from 1mA to 100mA. The device operates reliably within an extended temperature range of -40°C to 85°C. Its typical temperature drift is noted as 6mV (C temp).
Packaged in a compact SOT-23 (DBZ) surface-mount package, the TL431AIDBZTG4 is supplied in a standard reel quantity of 250 units. This makes it suitable for automated assembly processes in a variety of electronic designs, including on-board regulation and adjustable power supplies.
