2. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.

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.

Quiescent Bias Current − Current which is used to operate

the regulator chip and is not delivered to the load.
