<h2 id="heading-0">一、产品描述</h2>
<p>The TL431 is a three-terminal adjustable regulator series with a guaranteed thermal stability over</p>
<p>applicable temperature ranges. The output voltage may be set to any value between Vref and 36 volts with two external resistors. These device have a typical dynamic output impedance of 0.27Ω, Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications.</p>
