Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The guar-
anteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2:
Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
JMAX
(maximum junction
temperature),
θ
(junction to ambient thermal resistance) and T
(ambient temperature). The maximum power dissipation at any temperature is: PDiss

Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged di-
rectly into each pin.
Note 4:
Typical numbers are at 25C and represent the most likely parametric norm.
Note 5:
Limits are 100% production tested at 25C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 6:
Temperature coefficient is measured by the

method; i.e., the maximum
V
REF
is divided by the maximum
T.
Note 7:
Long term stability is V

25C measured during 1000 hrs.
Note 8:
Thermal hysteresis is defined as the change in +25C output voltage before and after cycling the device from 40C to 125C.
Note 9:
Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value measured with a 5V input.
