What is meant by the line regulation?
Line Regulation is the change in output voltage due to variation of the input voltage with all other factors held constant. It is expressed as a percent of the nominal output voltage. A power supply with tight line regulation delivers optimum voltages throughout the operating range.
What is line regulation with its formula?
Based on the line regulation characteristic, ΔVOUT is determined by the following formula: Typ. Max. In short, by the input voltage difference between 3 V and 4.2 V, the 1.8 V output changes by typically 0.432 mV / maximum 2.16 mV….

How does line regulation work?
Line regulation is the ability of the power supply to maintain its specified output voltage over changes in the input line voltage. It is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is the line and load regulation?
In line regulation output voltage is regulated when the input voltage changes. The purpose of load regulation is regulating output voltage when theload changes.
How do you find the line regulation?
How to Calculate Line Regulation
- Find the difference between the initial voltage and the maximum fluctuation.
- Divide the change in voltage by the initial voltage.
- Multiply the number obtained in Step 2 by 100.
What is line regulation in DC power supply?
Line regulation is a measure of the ability of the power supply or SMU to maintain the output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
How do you test line regulations?
How do you find line regulations?
Why is it important to determine the regulation of a line?
It is desirable for a power supply to maintain a stable output regardless of changes in the input voltage. The line regulation is important when the input voltage source is unstable or unregulated and this would result in significant variations in the output voltage.
How is regulator load regulation calculated?
Load regulation (percent) = 100 x (voltage no load — voltage full load) divided by voltage full load. Line regulation is another measure of voltage regulation.
What is good line regulation?
Line regulation is the ability of a power supply to maintain a constant output voltage despite changes to the input voltage, with the output current drawn from the power supply remaining constant. In practice, a well regulated power supply should have a line regulation of at most 0.1%.
What is the use of digital multimeter?
A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.
How to calculate line regulation?
How to Calculate Line Regulation. Step 1. Find the difference between the initial voltage and the maximum fluctuation . For example, if the initial voltage was 25 and the maximum Step 2. Step 3.
What is the formula for line regulation?
The line regulation gives the ability of a power supply to maintain the specified output voltage despite the changes or variations in the input line voltage. The value is calculated from the ratio of the change in the output voltage to the change in the input voltage, but usually expressed as a percentage: Line Regulation = ΔVo/ΔVi.
What is regulation of a transmission line?
Voltage regulation of transmission line is defined as the ratio of difference between sending and receiving end voltage to receiving end voltage of a transmission line between conditions of no load and full load. It is also expressed in percentage.
