TERMINOLOGY
Temperature Coefficient
The change of output voltage with respect to operating temper-
ature changes normalized by the output voltage at 25°C. This
parameter is expressed in ppm/°C and can be determined by
TCVOUT[ppm/°C]
=
( ) VOUT T2 VOUT
VOUT (25°C)× (T2
(T1 )
T1
)
×106
where:
VOUT (25°C) = VOUT at 25°C.
VOUT (T1) = VOUT at Temperature 1.
VOUT (T2) = VOUT at Temperature 2.
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
The typical shift of output voltage at 25°C on a sample of parts
subjected to a test of 1000 hours at 25°C.

where:
VOUT (t0) = VOUT at 25°C at Time 0.
VOUT (t1) = VOUT at 25°C after 1000 hours operation at 25°C.
Thermal Hysteresis
The change of output voltage after the device is cycled 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.

VOUT_TC = VOUT at 25°C after temperature cycle at +25°C to
−40°C to +125°C and back to +25°C.
