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
Note 11
Human body model 100 pF discharged through a 15 kX resistor
Note 12
See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ or the section titled ‘‘Surface Mount’’ found in a current National
Semiconductor Linear Data Book for other methods of soldering surface mount devices
