TERMINOLOGY
Dropout Voltage (V
Dropout voltage, sometimes referred to as supply voltage head-
room or supply output voltage differential, is defined as the
minimum voltage differential between the input and output
necessary for the device to operate, such as
Because the dropout voltage depends upon the current passing
through the device, it is always specified for a given load
current.
Temperature Coefficient (TCV
The temperature coefficient relates the change in output voltage
to the change in ambient temperature of the device, as normalized
by the output voltage at 25°C. This parameter is expressed in
ppm/°C and can be determined by the following equation:
where:

Output Voltage Hysteresis (ΔV
Output voltage hysteresis represents the change in output
voltage after the device is exposed to a specified temperature
cycle. This may be expressed as either a shift in voltage or a
difference in parts per million from the nominal output as
follows:
where:
V
V
Thermal hysteresis occurs as a result of forces exhibited upon
the internal die by its packaging. The effect is more pronounced
in parts with smaller packages.

Long-Term Stability (ΔV
Long-term stability refers to the shift in output voltage at 25°C
after 1000 hours of operation in a 25°C environment. This may
also be expressed as either a shift in voltage or a difference in
parts per million from the nominal output as follows:
where,

Line Regulation
Line regulation refers to the change in output voltage in
response to a given change in input voltage, and is expressed in
either percent per volt, parts per million per volt, or microvolt
per volt change in input voltage. This parameter accounts for
the effects of self-heating.
Load Regulation
Load regulation refers to the change in output voltage in
response to a given change in load current, and is expressed in
either microvolts per milliampere, parts per million per
milliampere, or ohms of dc output resistance. This parameter
accounts for the effects of self-heating.
