AZ431 - BCD Semiconductor

AZ431 ADJUSTABLE PRECISION SHUNT REGULATORS

The AZ431 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 www.DataSheet4U.com power supply, charger.
