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

Semiconductor Linear Data Book for other methods of soldering surface mount devices
