There are basic two types of voltage regulators viz., (i) series voltage regulator (ii) shunt voltage regulator. The series regulator is placed in series with In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents, and also The voltage regulation process is very easy by using the above three components. The first component of the voltage regulator like a feedback circuit is used to LINEAR VOLTAGE REGULATORS. Introduction. The linear regulator is the basic building block of nearly every power supply used in electronics. This provides a steadier dc voltage. Regulator: a circuit used to produces a constant dc output voltage by reducing the ripple to negligible amount. Two basic categories of voltage regulation are: • Line regulation circuit called a regulator maintains a nearly constant output voltage.
