TL431ID Description

Short technical summary and product information.

The TL431ID from Texas Instruments is a three-terminal adjustable shunt regulator designed for stable operation over various temperature ranges. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors.

Key electrical characteristics include a typical output impedance of 0.2Ω and a sink-current capability ranging from 1mA to 100mA. The device offers reference voltage tolerance options, with the B grade specified at 0.5% at 25°C.

Packaged in an 8-pin SOIC, the TL431ID operates from -40°C to 85°C. Its active output circuitry provides a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies.
