at which the regulator output no longer maintains regulation
against further reductions in input voltage. Measured when
the output drops 100 mV below its nominal value (which is
measured at 1.0 V differential), dropout voltage is affected
by junction temperature, load current and minimum input
supply requirements.
change in input voltage. The measurement is made under
conditions of low dissipation or by using pulse techniques such
that average chip temperature is not significantly affected.
