AN431BN-ATRE1

A Product Line of Diodes Incorporated AN431 ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AN431 series ICs are three-terminal adjustable shunt regulators with guaranteed thermal stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger and other adjustable regulators. (Top View) ANODE 3 The output voltage of these ICs can be set to any value between V REF (2.5V) and the maximum cathode voltage (36V). The AN431 precision reference is offered in two voltage tolerance: 0.5% and 1.0%. 1 2 CATHODE REF These ICs are available in SOT-23 package.
