The TL431AIDBVR is a three-terminal adjustable precision shunt regulator manufactured by Texas Instruments. It is designed for applications requiring stable voltage references, offering an adjustable output voltage that can be set anywhere between its internal reference voltage (Vref, approximately 2.5V) and 36V using two external resistors. This device operates reliably over a wide temperature range from -40°C to 125°C.
Key electrical characteristics include a typical voltage tolerance of 0.5% for the B grade at 25°C, a typical output impedance of 0.2Ω, and a sink current capability ranging from 1mA to 100mA. The device exhibits a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in various power management circuits.
Packaged in a SOT-23 (DBV) surface-mount package, the TL431AIDBVR is suitable for automated assembly processes. It is supplied in a 3000-unit reel, compatible with tape and reel packaging for high-volume manufacturing.
This shunt regulator is ideal for on-board regulation, adjustable power supplies, and other voltage reference applications where precise and stable output voltage is critical.
