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 using pulse techniques
such that the average chip temperature is not significantly
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
Input Bias Current – That part of the input current that is
not delivered to the load.
Output Noise Voltage – The rms AC voltage at the
output, with constant load and no input ripple, measured over
a specified frequency range.
Long Term Stability – Output voltage stability under
accelerated life test conditions with the maximum rated
voltage listed in the devices’ electrical characteristics and
maximum power dissipation.
