AS431
ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AS431 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) (Top View) ANODE
3 NC 1 * 2 CATHODE 3 (Note 4) The output voltage of AS431 can be set to any value between VREF
(2.5V) and the corresponding maximum cathode voltage (36V). 1 2 REF The AS431 precision reference is offered in two voltage tolerance:
0.5% and 1.0%.
This IC is available in 4 packages: TO92 (Ammo Packing), SOT23,
SOT25 and SOT89. 5 ANODE 4 REF CATHODE SOT23 SOT25 Note 4: * Pin 2 is attached to substrate and must be connected to ANODE or
