The TL431AIDR2G with Voltage References 2.5-36V ADJ 1-100mA is a shunt voltage regulator manufactured by ON Semiconductor. This electronic part is a 3-pin TO-92 packaged IC that features adjustable voltage references from 2.5-36V, and an adjustable current limit of up to 100mA. The TL431AIDR2G has a low total harmonic distortion, low temperature drift and its output is nearly independent of the operating voltage, making it ideal for precision applications. It is also designed to provide good line and load regulation that makes it suitable for battery-operated applications, such as portable audio.
