DESCRIPTION

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 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 a typical output

impedance of 0.25Ω. Active output circuitry supplies a very sharp

turn-on characteristic, which makes the UTC ULVH431 very good

substitute for low-voltage Zener diode in many applications such as

adjustable power supplies and on-board regulation.
