The capacitors are placed as near as possible to the current sink to minimize the resistive effects of the trace (or wire) connecting the IC to the supply. Why couldn't I just use a regulator for this purpose?
So by adding a small capacitor - which conducts lots of current fast, but only for a short time - we can alter the overall behaviour of the circuit. Another way of thinking about it is that we're adding a certain amount of overshoot to the voltage correction, counteracting the op amp's own tendency to overshoot.
Ultracapacitors, which can economically supply high currents and deliver large amounts of power in time frames as long as a few minutes, can thus act as a supplemental power supply to stabilize the network voltage during the start of a machine. Therefore, the main power supply will be minimally affected.
Ultracapacitors can be applied in various industries and in different ways for voltage stabilization. If a process results in large voltage swings over a timeframe ranging from sub- second to a few minutes, ultracapacitors can be considered as a potential solution.
Those capacitors are called decoupling/bypass capacitors. Decoupling = isolate from noise, bypass = provide local energy for when fast switching digital signals require it. The voltage regulator cannot respond instantaneously to changes in power requirements, resulting in a momentary dip in voltage when current demands increase.
Energy storage technologies such as batteries have been proposed to resolve these voltage stabilization issues. Although batteries can store and release a large amount of energy over extended time periods, they have difficulty in providing the short-term high power levels required for voltage stabilization.
