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 100mV below its nominal value, 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 volt- age. 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. The measurement is

made under conditions of low dissipation or by using pulse techniques such that average chip temperature 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.
