... If the circuit is connected directly to the 110V/230VAC mains, VIN can reach quite high levels up to 350V peak. So existing designs require a lot of additional devices, in order to reduce the incoming voltage to an acceptable level; they further require electrolytic capacitors to keep that voltage c ...

CIRCUIT FUNCTION AND BENEFITS CIRCUIT DESCRIPTION
... If the resistors are perfectly matched, the input voltage, VREF, appears across R1, thereby producing a constant load current, IO, which is equal to VREF/R1. The AD8603 op amp is used in the feedback loop of the circuit and was chosen because of its low bias current (maximum 1 pA) and offset voltage ...

Voltage regulator
A voltage regulator is designed to automatically maintain a constant voltage level. A voltage regulator may be a simple ""feed-forward"" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line.
