前几天测试了 参考电压源 TL431 的负载电容稳定性。为了得到该器件稳定特性，下面使用ADALM2000 测量它的环路频率特性。 二、测试电路 这是TL431测试电路。 在面包板上搭建这个电路。在开始的时候没有添加负载电容。使用小型高频变压器 在TL431的 ...

(Although we think he really made it for the fun of making it.) The circuit is centered around a TL431 programmable shunt regulator, which is an awesome and underrated chip in its own right.

We like the instrument, and the use of the TL431 in an unexpected manner is the cherry on the cake. Here’s a previous Rogowski circuit using more conventional parts. You can dive a bit more into ...
