TERMINOLOGY
Temperature Coefficient
Temperature coefficient is the change of output voltage with
respect to operating temperature changes, normalized by the
output voltage at 25°C. This parameter is expressed in ppm/°C
and can be determined by the following equation:
where:
V
V
V
Line Regulation
Line regulation is the change in output voltage due to a
specified change in input voltage. This parameter accounts for
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
Load regulation is the change in output voltage due to a
specified change in load current. This parameter accounts for
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
Long-term stability is the typical shift of output voltage at 25°C
on a sample of parts subjected to a test of 1000 hours at 25°C.

Thermal Hysteresis
Thermal hysteresis is defined as the change of output voltage
after the device is cycled through temperature from +25°C to
−40°C to +125°C and back to +25°C. This is a typical value
from a sample of parts put through such a cycle.
