Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating range indicates conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions see 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 human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 3:
At elevated temperatures, devices must be derated based on thermal resistance. The device in the SO-8 package must be derated at
θ

junction to ambient with no heat sink.
Note 4:
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 5:
VIN is defined as the VIN = AVIN = PVIN
Note 6:
Quiescent current defined as the current flow into AVIN.
Note 7:
Load regulation is tested by using a 10ms current pulse and measuring V
