DEFINITIONS
Dropout Voltage
- The input/output voltage differential 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.
Line Regulation
- The change in output voltage for a
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.
Load Regulation
- The change in output voltage for a
change in load current at constant chip temperature.
Maximum Power Dissipation
- The maximum total device
dissipation for which the regulator will operate within
specifications.
Supply Current
- Current which is used to operate the
regulator chip and is not delivered to the load.
