What is line regulation / how is it calculated?

Make and record the following measurements with rated output load at 25oC

  • Output voltage at nominal line (input) voltage. Vout N
  • Output voltage at high line (input) voltage. Vout H
  • Output voltage at low line (input) voltage. Vout L

The line regulation is Vout M (the maximum of the two deviations of output) from the value at nominal input in percentage. Line regulation calculation
