Definition of Terms
Dropout Voltage: The input-output voltage differential at which the circuit ceases to regulate against further reduction in input voltage.
Measured when the output voltage has dropped 100mV from the normal voltage obtained at 14V input, dropout voltage is dependent
upon load current and junction temperature.
Input Voltage: The DC voltage applied to the input terminals with respect to ground.
Input-Output Differential: The Voltage difference between the unregulated input voltage and the regulated output voltage for which the
regulator will operate.
Line Regulation: The change in output voltage for a change in the input voltage. The measurement is made under conditions of low
dissipation or by usung pulse techniques such that the average chip temperature is not significantly affected.
Load Regulation: The change in output voltage for a change in load current at constant chip temperature.
Long Term Stability: Output voltage stability under accelerated life-test conditions after 1000 hours with max. rate voltage and junction
temperature.
Output Noise Voltage: The rms AC voltage at the output, with constant load and no input ripple, measured over a specified frequency range.
Quiescent Current: That part of the positive input current that does not contribute to the positive load current. The regulator ground
lead current.
Ripple Rejection: The ratio of the peak-of-peak input ripple voltage to the peak-of-peak output ripple voltage at a specified frequency.
