Voltage regulator is developed for the purpose of maintain a constant level of voltage automatically. This can be a device that is designed for only feed forward or it can also be designed for controlling negative controlled loops. This chip can either make use of electric components or it can make use of some electromechanical mechanism. As per the design of the device, it can be made used for regulating one or more of DC or AC voltages. These chips can be found in the part of the power supplies of the computer, where the DC voltages can be stabilized which is made used by processors and also other components. The voltage generators are made used in the generator plants of the central – power station and also the automobile alternators for controlling the output. In a power distribution system, these devices are installed along with the distribution lines and also at the places of substations. This is done for receiving voltage in a steady manner without regard to the amount of power that is drawn from line. There are various parameters that are meant for the effectiveness and quality of the voltage regulator. Utsource.net is a good platform for you to learn in depth about the voltage regulator chips.



Load regulation is the parameter that indicates the variation in the output voltage for the purpose of a given change that can be found in load current. Line regulation is another parameter that is made used for checking the quality of voltage regulator. This parameter measures the amount to which the output voltage varies as per the variation in the input voltage.


There are many other parameters too available that can be made used for the purpose of measuring the quality of the voltage regulator. Temperature coefficient is the parameter that measures the output voltage that can be made used for recording the variation in the temperature. Initial accuracy is the parameter that is capable of reflecting the error associated with output voltage for a particular regulator that does not consider the effects of temperature or aging. Dropout voltage can be considered as the minimum amount of difference that exists between the output and the input voltage. A voltage regulator with lower dropout value so supposed to be the one that is designed for working well even with least amount of input voltage which can be one volt or a bit above it. Absolute maximum ratings are the ones defined for the purpose of regulator components which are meant for specifying the peak and the continuous output currents.


Output noise is a parameter that is specified in the form of graph versus frequency. The output ripples are given the form of RMS or peak to peak voltages. Quiescent current in the case of a voltage regulator is the amount of the current that is drawn internally and which is not available for load. Transient response is another parameter that is associated with the voltage regulator that is meant for the purpose of measuring the reaction of the regulator at the time of a rapid change in input voltage.
