Load Regulation
current at a constant temperature.
Dropout Voltage
no longer maintains regulation against further reductions in
input voltage. Measured when the output drops 2% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Output Noise Voltage
specified frequency range. Input voltage and output load
current are kept constant during the measurement. Results
are expressed in mV
Disable and Ground Current
the ground pin when the regulator operates with a load on its
output. This consists of internal IC operation, bias, etc. It is
actually the difference between the input current (measured
through the LDO input pin) and the output load current. If
the regulator has an input pin that reduces its internal bias
and shuts off the output (enable/disable function), this term
is called the disable current (I

application circuits are shown in Figures 4 and 5.

Higher capacitance and lower ESR will improve the overall
line transient response.
Output Decoupling (C
a minimum Equivalent Series Resistance (ESR) for the
output capacitor. The minimum output decoupling value is
1.0 mF and can be augmented to fulfill stringent load
transient requirements. The regulator works with ceramic
chip capacitors as well as tantalum devices. Larger values
improve noise rejection and load regulation transient
response. Figure 30 shows the stability region for a range of
operating conditions and ESR values.

Line Regulation
The measurement is made under conditions of low
dissipation or by using pulse techniques such that the
average junction temperature is not significantly affected.
Line Transient Response
response when the input voltage is excited with a given
slope.
Load Transient Response
response when the output current is excited with a given
slope between no−load and full−load conditions.
Thermal Protection
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated at typically 175°C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.

output, there is no resistor divider. If the part is enabled
under no−load conditions, leakage current through the pass
transistor at junction temperatures above 85°C can approach
several microamps, especially as junction temperature
approaches 150°C. If this leakage current is not directed into
a load, the output voltage will rise up to a level
approximately 20 mV above nominal.
