TERMINOLOGY
Temperature Coefficient
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
where:
V
V
V
Line Regulation
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
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
Typical shift of output voltage at 25°C on a sample of parts
subjected to a test of 1,000 hours at 25°C.

Thermal Hysteresis
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.
