AZ431-A is a three-terminal adjustable shunt regulator located on the Avalon board, which can guarantee thermal stability over the entire operating range, and the silkscreen mark is EA1. Its sharp turn-on characteristics, low-temperature coefficient, and low output impedance make it an ideal replacement for Zener diodes in applications such as switching power supplies, chargers, and other adjustable voltage regulators. The AZ431AN-ATRE1 is available in two voltage tolerances of 0.4% and 0.8%, and it comes in a SOT23 package.

Feature:

• Programmable accurate output voltage from 2.5V to 36V.

• High stability under capacitive load

• Low Temperature Offset: 4.5mV (Typical).

• Low equivalent full-range temperature coefficient (20PPM/°C typical).

• Sink current capability from 1mA to 100mA.

• Low output noise

• Wide operating range from -40 to +125°C

Applications:

• Charger

• Voltage adapter

• Switching power supply

• Graphic card

• Precision voltage reference
