Then the regulator chip provides a self-contained, feedback controlled mechanism to keep the output voltage at the specified value.</p> <p>The output capacitor further smooths any output ripple and provides a reservoir of charge to supply any surge in current load that may be encountered.</p> <p>This example includes a load resistor that allows the exploration of the effects of load. The load is varied during the simulation and it can be seen that above a load of 100 mA, the regulation of the output voltage begins to deteriorate.</p> <p>The addition of a few components can make it possible for such a circuit to provide significantly higher power loads. See http://www.systemvision.com/design/ac-dc-power-adapter-current-boost-regulator for an example.</p> About text formats Tags PowerVoltage RegulatorAC-DC Convertertransformerpower supply Select a tag from the list or create your own.Drag to re-order taxonomy terms.
