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 ...

A shunt regulator acts as the feedback element in a low-pass Sallen-Key filter, converting a 5-V PWM signal to a dc value between –2.5 V and 2.5 V based on duty cycle.
