AS431H ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AS431H is a three-terminal adjustable shunt regulator with guaranteed thermal stability over a full operation range. It features (Top View) sharp turn-on characteristics, low temperature coefficient and low ANODE output impedance, which make it ideal substitute for Zener diode in 3 applications such as switching power supply, charger and other adjustable regulators. The output voltage of AS431H can be set to any value between V REF (2.495V) and the corresponding maximum cathode voltage (36V). 1 2 The AS431H precision reference is offered in two voltage tolerance: REF CATHODE 0.5% and 1.0%. SOT23 (Normal Pin-out) This IC is available in 2 packages: TO92 (Ammo Packing) and SOT23.
