Description

The AZ431-A 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 AZ431-A can be set to any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V). The AZ431-A precision reference is offered in two voltage tolerance: 0.4% and 0.8%.

Application(s)

  • Charger
  • Voltage Adapter
  • Switching Power Supply
  • Graphic Card
  • Precision Voltage Reference

Feature(s)

  • Programmable Precise Output Voltage from 2.5V to 36V
  • High Stability under Capacitive Load

Our shunt voltage regulator portfolio includes 2.5V, 1.24V, and 0.6V reference voltage devices covering consumer, computing, industrial, and automotive applications.

It includes industry standard TL431 and TL432 equivalents, as well as footprint compatible, very low minimum (knee) current for latest low standby power isolated power supplies. Additionally, it includes a well enhanced operating voltage range TLV431 (1.24V) equivalents. All of the 2.5V and 1.24V support operating temperatures up to 125°C as standard, therefore reducing the number of variants that need to be qualified and stocked.

Automotive-compliant variants are available which are qualified to AEC-Q100 Grade 1 in IATF 16949 facilities supporting PPAP documentation.
