A power regulator or 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.

Do 5v regulators always get hot?

There are several factors that affect the heat output of a voltage regulator. A linear regulator such as a 7805 series will pass the same amount of current as the load draws. The regulator will also have a certain voltage across it and can be calculated by subtracting the output voltage (5V in this case) from the source voltage. The source voltage might be anywhere from 7 volts up to as much as 30 volts. The heat generated in the regulator can be calculated using the power equation, power = current x voltage. As stated above, the current is dependant on the load. As the current increases, so the power dissipated in the regulator increases. Similarly, as the source voltage increases, so does the power dissipated by the regulator. The regulator will always show a temperature rise but how hot it gets depends on how effectively the heat is drawn away from the regulator. If the regulator is mounted on an effective heat sink, it can dissipate large amounts of heat without becoming hot. Without a heatsink, the same regulator in the same situation will become far hotter. All regulators have certain limits for power dissipation and temperature. The data sheet will have information on the limits and they should always be noted during a design phase.


In a DC circuit is there an alternate to rheostat for controlling the battery voltage?

In a DC circuit, one alternate to the rheostat for controlling battery voltage is a voltage regulator. You could build a linear regulator, but you need to consider the power that might be dissipated - this would be the same amount of power dissipated by the rheostat. You could also build a switching regulator - this would be more complex, but it could be more efficient because the dissipation across the regulator would be less.


What is avr in turbo generator in thermal power plant?

AVR stands for automatic voltage regulator.


What is the working principle of fan regulator?

n electrical regulator by using resistance the output voltage is varied simultaneously the speed is varied... But to reduce the the energy loses in the resistor, electronic regulator is introduced,which uses triac to vary the output voltage by varying the firing angle.Which avoids lose of energy in resistor...


How much does a voltage regulator cost?

This is dependent on what you're looking for in voltage and power rating. Small IC's can be purchased for ~$1.00.

Only if you change out the entire regulator. The power regulator unit is pitched a little different due to the power motor components.
