2.Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately.
Pulse testing with low duty cycle is used.
DEFINITIONS
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 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 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.
