Description
ULVH431G-AB3-R UTC Low Voltage Precision Adjustable Shunt Regulator 16V 1% SOT-89 RoHS
The UTC ULVH431 is a low-voltage 3-terminal programmable shunt regulator with guaranteed thermal stability over full applicable industrial and commercial temperature ranges. The output voltage of UTC ULVH431 can be set to any value between V REF (1.24V) and the corresponding maximum cathode voltage (18V) with two external resistors. The device operates from a lower voltage (1.24V) than the widely used TL431 and TL1431 shunt-regulator references. 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.
