Take advantage of current control topologies without self-heating error while retaining the 317/337's fault protection ...

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 ...

1. 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.

Active supercapacitor balancing tends to mean something similar to passive balancing in batteries – either shunt regulators that clamp the maximum voltage across each individual cell in the string, or ...
