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 such that average chip temperature is not significantly which the regulator output no longer maintains regulation affected. against further reductions in input voltage. Measured when Load Regulation The change in output voltage for a the output drops 100 mV below its nominal value (which is change in load current at constant chip temperature. measured at 1.0 V differential), dropout voltage is affected Maximum Power Dissipation The maximum total device by junction temperature, load current and minimum input dissipation for which the regulator will operate within supply requirements. specifications. Line Regulation The change in output voltage for a Quiescent Bias Current Current which is used to operate change in input voltage. The measurement is made under the regulator chip and is not delivered to the load. conditions of low dissipation or by using pulse techniques
