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 the Electrical Characteristics. The
guaranteed 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:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
(maximum junction temperature),
θ
JA
(junction to am-
bient thermal resistance), and T
(ambient temperature). The maximum allowable power dissipation at any temperature is P
= (T
T
)/
θ
or the number
given in the Absolute Maximum Ratings, whichever is lower. The typical thermal resistance (
θ
JA
) when soldered to a printed circuit board is approximately 306C/W
for the M5 package.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor 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 Averaging Outgoing Quality Level (AOQL).
Note 6:
Actual test is done using equivalent current sink instead of a resistor load.
Note 7:
V
SAT
= V(IN) V
OUT
, when the voltage at the IN pin is forced 100 mV above the nominal regulating voltage (V
REG
).
Note 8:
See Applications and Typical Performance Characteristics sections for information on this resistor.
