VOLTAGE REGULATOR DESIGN DEVELOPMENT TESTING


provides a stable DC voltage independent of the load current, temperature and AC line voltage variations. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. There are two types of voltage regulators: linear and switching.
