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 power supply, charger and other adjustable regulators.
The AZ431 series ICs contain two voltage types,AZ431-A for 40V and AZ431-B for 20V. The output voltage of both types can be set to any value between VREF(2.5V) and the corresponding maximum cathode voltage.
The AZ431 precision reference is offered in two band-
gap tolerance: 0.4% and 0.8%.
These ICs are available in 5 Packages: TO-92, SOT-23-
3, SOT-23-5, SOT-89 and SOIC-8.
