The HGSEMI TL431AM/TR manufactured with Voltage References SOP-8 RoHS is a three-terminal adjustable shunt regulator IC. This device features an internal bandgap reference, a comparator, and an effective series resistance and a temperature compensation network. It can adjust its output voltage between an upper and lower voltage limit with a single external resistor. This IC has an operating current of 5 mA and an operating voltage range from 4.75 to 36 V. It has excellent temperature stability and line regulation. The TL431AM/TR can be used as an adjustable precision voltage reference, current regulator, and as an adjustable system voltage regulator. It is an ideal choice for low-power, low-voltage applications.
