AS431HAZTR-G1

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