Product Brief ADJUSTABLE PRECISION SHUNT REGULATORS Description
The AZ431-A 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-A series ICs are of 40V voltage type. Its output voltage can be set to any value between VREF(2.5V) and 36V. The AZ431-A precision reference is offered in two bandgap tolerance: 0.4% and 0.8%.

The voltage reference operates as a low temperature coefficient zener which is programmable between V REF(2.5V) and 36 volts using two external resistors. The device has a wide operating current range of 1 mA to 100mA and a typical dynamic impedance of 0.2W.

光耦
光耦合器一般由三部分组成：光的发射、光的接收及信号放大。输入的电信号驱动发光二极管（LED），使之发出一定波长的光，被光探测器接收而产生光电流，再经过进一步放大后输出。这就完成了电—光—电的转换，从而起到输入、输出、隔离的作用。由于光耦合器输入输出间互相隔离，电信号传输具有单向性等特点，因而具有良好的电绝缘能力和抗干扰能力。又由于光耦合器的输入端属于电流型工作的低阻元件，因而具有很强的共模抑制能力。所以，它在长线传输信息中作为终端隔离元件可以大技能大培训常提用模高拟器件信介绍噪比。

Description
The LM431A/LM431B/LM431C are three terminal output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2Ω Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.
