TERMINOLOGY
Line Regulation
Line regulation refers to the change in output voltage due to a
specified change in input voltage. It includes the effects of self-
heating. Line regulation is expressed as percent-per-volt, parts-
per-million-per-volt, or microvolts-per-volt change in input
voltage.
Load Regulation
The change in output voltage is due to a specified change in
load current and includes the effects of self-heating. Load
regulation is expressed in microvolts-per-milliampere, parts-
per-million-per-milliampere, or ohms of dc output resistance.
Long-Term Stability
Long-term stability refers to the typical shift of output voltage at
25°C on a sample of parts subjected to a test of 1000 hours at
125°C.

Temperature Coefficient
Temperature coefficient is the change of output voltage over
the operating temperature change, normalized by the output
voltage at 25°C, expressed in ppm/°C. The equation follows:

NC = no connect.
There are internal connections at NC pins that are reserved for
manufacturing purposes. Users should not connect anything at
the NC pins.
Thermal Hysteresis
Thermal hysteresis is defined as the change of output voltage
after the device is cycled through temperatures from +25°C to
−40°C, then to +85°C, and back to +25°C. This is a typical value
from a sample of parts put through such a cycle.
