Note 1:
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.
Note 2:
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.
Note 3:
Human body model, 100 pF discharged through a 1.5 k
X
resistor. Machine model, 200 pF discharged directly into each pin.
Note 4:
Thermal resistance of the SOT-23 package is specified without a heat sink, junction to ambient.
Note 5:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 6:
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 7:
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 8:
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 9:
Quiescent current is defined in the circuit of Figure 1.
Note 10:
For best long-term stability, any precision circuit will give best results if the unit is aged at a warm temperature, and/or temperature cycled for at least 46
hours before long-term life test begins. This is especially true when a small (Surface-Mount) part is wave-soldered; allow time for stress relaxation to occur. The
majority of the drift will occur in the first 1000 hours at elevated temperatures. The drift after 1000 hours will not continue at the first 1000 hour rate.
