Minimum load current

  1. In the datasheets for regulators does a minimum load current represent the
    minimum current needed to turn on the regulator?

    Thanks,
    Jon
     
  2. I believe that means the minimum current to have the output voltage within
    spec.
     
  3. For linear regulators, like the 78xx family, it is the minimum current
    at which the regulator will meet its specifications. How it fails to
    meet specs at lower currents is unspecified. :)

    In practice, I don't recall ever seeing a 78xx-type regulator that
    produced an out-of-spec voltage with only a DVM as a load.
