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 ...

In a typical voltage-regulator application, adding two external resistors, R A and R B, sets the shunt-regulated output voltage at the lower end of load resistor R S (Figure 1b). Figure 1 Despite the ...

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 ...

The circuit is centered around a TL431 programmable shunt regulator, ... Ralph’s simple battery charger is essentially this simple voltage regulator circuit.
