TERMINOLOGY
Temperature Coefficient
The change in output voltage with respect to operating
temperature change normalized by the output voltage at 25°C.
This parameter is expressed in ppm/°C and can be determined
as follows:
where:
V
V
V
Line Regulation
The change in the output voltage due to a specified change
in input voltage. This parameter accounts for the effects of
self-heating. Line regulation is expressed in percent per volt,
parts-per-million per volt, or microvolts per voltage 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 microvolts per milliampere,
parts-per-million per milliampere, or ohms of dc output
resistance.

Thermal Hysteresis
The change in output voltage after the device is cycled through
temperatures 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.
