TERMINOLOGY
Dropout Voltage (V
Dropout voltage, sometimes referred to as supply voltage
headroom or supply-output voltage differential, is defined as
the minimum voltage differential between the input and output
necessary for the device to operate.
Since 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 normal-
ized by the output voltage at 25°C. This parameter is expressed
in ppm/°C and can be determined by the following equation:

Thermally Induced Output Voltage Hysteresis (ΔV
Thermally induced 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 ppm from the nominal output.
where:
V
V
Thermal hysteresis occurs mainly 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
ppm from the nominal output.
where:

Line Regulation
Line regulation refers to the change in output voltage in
response to a given change in input voltage. It is expressed in
either percent per volt, ppm 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 milliamp, ppm per milliamp, or ohms
of DC output resistance. This parameter accounts for the effects
of self-heating.
