DEFINITIONS
Load Regulation
The change in output voltage for a change in output current
at a constant temperature.
Dropout Voltage
The input/output differential at which the regulator output
no longer maintains regulation against further reductions in
input voltage. Measured when the output drops 3% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Maximum Power Dissipation
The maximum total dissipation for which the regulator will
operate within its specifications.
Quiescent Current
The quiescent current is the current which flows through the
ground when the LDO operates without a load on its output:
internal IC operation, bias, etc. When the LDO becomes
loaded, this term is called the Ground current. It is actually the
difference between the input current (measured through the
LDO input pin) and the output current.
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 technique such that the average chip
temperature is not significantly affected.
Line Transient Response
Typical over and undershoot response when input voltage is
excited with a given slope.
Maximum Package Power Dissipation
The maximum power package dissipation is the power
dissipation level at which the junction temperature reaches its
maximum operating value, i.e. 125
°
C. Depending on the
ambient power dissipation and thus the maximum available
output current.
