- The voltage regulator is a helpful and most common IC building block next to the op amp. The monolithic form of a voltage regulator has replaced the discrete version because of their advantages. The monolithic voltage regulator is uniquely suited for local regulation.
- Therefore IC voltage regulators are invariably used now a day in almost all voltage regulators.
- The integrated circuit (IC) voltage regulator is an electronic integrated device which gives a constant voltage in any case of changes in the load circuits.
- The output voltage is regulated by the internal circuit so that it is comparatively independent of the current drawn by the load, the line or supply voltage and ambient temperature.
- An IC based voltage regulator can be classified in different ways. A common type of classification is three terminal voltage regulator and five or multi terminal voltage regulator.
- Another popular way of classifying IC voltage regulator is by identifying them as linear voltage regulator and switching voltage regulator.
