The TL431AIDRG4 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 TL431AIDRG4 is housed in an 8-pin SOIC package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The regulator offers a reference voltage tolerance of 0.5% at 25°C for the B grade, 1% for the A grade, and 2% for the standard grade. Its active output circuitry ensures 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.
This part is obsolete and no longer in production. An alternate part, TL431AIDR, offers upgraded functionality and is a drop-in replacement.
