Thus it is both an astonishingly versatile device for a designer and the ideal platform for anyone wanting to learn about or experiment with a regulator. Block diagram of a 723 regulator.

Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with ... circuit and voltages add up to the supply voltage. Components that are connected on ...

The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage, \({V_s}\).
