These specifications also apply from +2˚C to T
MAX
in the circuit of
Figure 1.
Specifications in
boldface
apply over the full rated temperature range.
Note 2:
Thermal resistance of the TO-46 package is 400˚C/W, junction to ambient, and 24˚C/W junction to case. Thermal resistance of the TO-92 package is
180˚C/W junction to ambient. Thermal resistance of the small outline molded package is 220˚C/W junction to ambient. Thermal resistance of the TO-220 package
is 90˚C/W junction to ambient. For additional thermal resistance information see table in the Applications section.
Note 3:
Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating effects can be
computed by multiplying the internal dissipation by the thermal resistance.
Note 4:
Tested Limits are guaranteed and 100% tested in production.
Note 5:
Design Limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage ranges. These limits are not used to
calculate outgoing quality levels.
Note 6:
Specifications in
boldface
apply over the full rated temperature range.
Note 7:
Accuracy is defined as the error between the output voltage and 10mv/˚C times the device’s case temperature, at specified conditions of voltage, current,
and temperature (expressed in ˚C).
Note 8:
Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device’s rated temperature
range.
Note 9:
Quiescent current is defined in the circuit of
Figure 1.
Note 10:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions. See Note 1.
