The TL431ILP is a three-terminal adjustable shunt regulator manufactured by Texas Instruments. It provides a stable output voltage that can be precisely set between its reference voltage (approximately 2.5V) and 36V using two external resistors. This device is designed for thermal stability over automotive, commercial, and military temperature ranges.
Key electrical characteristics include a reference voltage tolerance of 0.5% (B grade) at 25°C, a typical output impedance of 0.2Ω, and a sink current capability ranging from 1mA to 100mA. The operating temperature range is specified from -40°C to 125°C, making it suitable for demanding applications.
The TL431ILP features active output circuitry for a sharp turn-on characteristic, serving as an effective replacement for Zener diodes. Its applications include on-board regulation, adjustable power supplies, and switching power supplies. The device is available in a TO-92 package suitable for through-hole mounting.
Environmental compliance includes RoHS3 compliance and REACH unaffected status, with a Moisture Sensitivity Level (MSL) of 1.
