1. Description

The AZ431BN-ATRE1 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. The output voltage of AZ431BN-ATRE1 can be set to any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V). The AZ431BN-ATRE1 precision reference is offered in two voltage tolerance: 0.4% and 0.8%. This IC is available in 3 packages: TO92 (Bulk or Ammo Packing), SOT23 and SOT89.
