An unusual switching capacitive shunt regulator from Supertex can cut mains stand-by power to less that 20mW. It replaces the traditional Zener diode with a mosfet switch in a capacitively-coupled ...

Developed as a three-terminal shunt regulator, the popular and multiple-sourced TL431 IC offers designers many intriguing possibilities beyond its intended application. Internally, the TL431 comprises ...

Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al.) can be used in shunt regulator topologies can sometimes inspire “new fangled” circuit designs. Figure 1 shows ...

This file type includes high-resolution graphics and schematics when applicable. Did you know that your shunt regulator is in danger? Don’t worry—the fix is free (and free is good). A feedback circuit ...
