TERMINOLOGY
Temperature Coefficient (TCV
The change of output voltage over the operating temperature
change and normalized by the output voltage at 25°C, expressed
in ppm/°C. The equation follows
where:
V
V
V
Line Regulation (ΔV
The change in output voltage due to a specified change in input
voltage. It includes the effects of self-heating. Line regulation is
expressed in either percent per volt, parts per million per volt,
or microvolts per volt change in input voltage.
Load Regulation (ΔV
The change in output voltage due to a specified change in load
current. It includes the effects of self-heating. Load regulation
is expressed in either microvolts per milliampere, parts per
million per milliampere, or ohms of dc output resistance.
Long-Term Stability (ΔV
Typical shift of output voltage at 25°C on a sample of parts
subjected to an operation life test of 1000 hours at 125°C.

Thermal Hysteresis (V
The change of output voltage after the device is cycled through
temperatures from +25°C to −40°C to +85°C and back to +25°C.
This is a typical value from a sample of parts put through
such a cycle
where:

Parts can deviate from their specified performance outside the
specified temperature range.
