The TL431AID is a three-terminal adjustable shunt regulator from STMicroelectronics, 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. This device features a typical output impedance of 0.2Ω and a sink-current capability ranging from 1mA to 100mA.
The TL431AID is housed in an 8-pin SOIC package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The active output circuitry provides a sharp turn-on characteristic, making it an effective replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies.
Key specifications include a reference voltage tolerance of 1% at 25°C. The device is RoHS3 compliant, REACH unaffected, and has an MSL rating of Level 1.
