The circuit can also serve as a high-current shunt regulator, though with stability caveats. The circuit is stable with a load capacitance below about 1nF or above about 200µF. The circuit can be ...

A feedback circuit commonly used in isolated dc-dc converter applications uses a shunt regulator (such as the ATL431) and an optical isolator to feed the output voltage back to the pulse-width ...

The two shunt regulator circuit examples were not optimized to minimize short-circuit currents. Nevertheless, both circuits clearly minimize the possible heating from short-circuit currents when ...
