TL431AIDR Description

Short technical summary and product information.

The TL431AIDR 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. This device features a typical output impedance of 0.2Ω and a sink current capability ranging from 1mA to 100mA.

The TL431AIDR is available in an 8-pin SOIC package, suitable for through-hole mounting. It operates within a temperature range of -40°C to 85°C. The 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.

Key electrical characteristics include a reference voltage tolerance of 1% at 25°C. The device is designed for specified thermal stability, making it reliable for commercial and industrial applications.
