DEFINITIONS
Load Regulation
The change in output voltage for a change in output
current at a constant chip 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 100 mV
below its nominal value (which is measured at 1.0 V
differential value). The dropout level is affected by the chip
temperature, load current and minimum input supply
requirements.
Output Noise Voltage
This is the integrated value of the output noise over a
specified frequency range. Input voltage and output current
are kept constant during the measurement. Results are
expressed in m VRMS.
Maximum Power Dissipation
The maximum total dissipation for which the regulator
will operate within its specs.
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
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. One usually
distinguishes static line regulation or DC line regulation (a
DC step in the input voltage generates a corresponding step
in the output voltage) from ripple rejection or audio
susceptibility where the input is combined with a frequency
generator to sweep from a few hertz up to a defined
boundary while the output amplitude is monitored.
Thermal Protection
Internal thermal shutdown circuitry is provided to protect
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated at typically 125 ° C,
the regulator turns off. This feature is provided to prevent
catastrophic failures from accidental overheating.
Maximum Package Power Dissipation
The maximum power package power dissipation is the
power dissipation level at which the junction temperature
reaches its maximum operating value, i.e. 125 ° C.
Depending on the ambient temperature, it is possible to
calculate the maximum power dissipation and thus the
maximum available output current.
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.
