General
duty cycle techniques to maintain junction temperature as
close as possible to ambient temperature.
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.
Load Regulation
current at a constant temperature.
Dropout Voltage
output no longer maintains regulation against further
reductions in input voltage. Measured when the output drops
100 mV below its nominal value. The junction temperature,
load current, and minimum input supply requirements affect
the dropout level.
Ground and Disable Currents
ground pin when the regulator operates without a load on its
output (I
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

Turn−on and Turn−off Times
power−up of the device from the moment when input
voltage reaches 90% of its operating value to the moment
when output voltage reaches 90% of its nominal value at
specific output current or resistive load.
power−down of the device from the moment when input
voltage drops to 10% of its operating value to the moment
when output voltage drops to 10% of its nominal value at
specific output current or resistive load.
Enable and Disable Times
power−up of the device from the moment when enable
voltage reaches 90% of input voltage operating value to the
moment when output voltage reaches 90% of its nominal
value at specific output current or resistive load.
power−down of the device from the moment when enable
voltage drops to 10% of input voltage operating value to the
moment when output voltage drops to 10% of its nominal

Line Transient 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.
Maximum Package Power Dissipation
