Definitions

Dropout Voltage

The input/output voltage differential at which the regu-

lator output no longer maintains regulation against

further reductions in input voltage. Measured when the

output drops 100mV below its nominal value, dropout

voltage is affected by junction temperature, load cur-

rent 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, so

that average chip temperature is not significantly af-

fected.

Load Regulation

The change in output voltage for a change in load cur-

rent at constant chip temperature. The measurement

is made under conditions of low dissipation or by us-

ing pulse techniques, so that average chip tempera-

ture is not significantly affected.

Maximum Power Dissipation

The maximum total device dissipation for which the

regulator will operate within specifications.

Quiescent Bias Current

Current which is used to operate the regulator chip

and is not delivered to the load.
