PARAMETER DEFINITIONS
Temperature Coefficient (TCV
O
)
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:

Line Regulation (
V
O
/
V
IN
)
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 (
V
O
/
I
LOAD
)
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
of dc output resistance.
Long-Term Stability (

Thermal Hysteresis (V
O_HYS
)
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:

Operating Temperature
The temperature extremes at which the device can still function.
Parts may deviate from their specified performance outside the
specified temperature range.
