- DESCRIPTION
The UTC ULVH431 is a low-voltage 3-terminal programmable shunt regulator with guaranteed thermal stability over full applicable industrial and mercial temperature ranges.
The output voltage of UTC ULVH431 can be set to any value between VREF (1.24V) and the corresponding maximum cathode voltage (18V) with two external resistors.
The UTC ULVH431 is an ideal voltage reference in isolated feedback circuits for 3-V to 3.3-V switching-mode power supplies when it is used with an opto-coupler. It has...
