Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

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.

maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5mA to four. Under normal

operating conditions the maximum current that pins 2, 4 or 5 can handle is limited to 5mA each.

package types when board mounted follow:

Note 4: The human body model is a 100pF capacitor discharge through a 1.5k

Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly

into each pin.

Note 5: See the URL ”http://www.national.com/packaging/“ for other recommendations and methods of soldering surface mount devices.

Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 8: Care should be taken to include the effects of self heating when setting the maximum output load current. The power dissipation of the LM27 would increase

about 0.32˚C due to self heating. Self heating is not included in the trip point accuracy specification.

Note 9: The 1µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the current for every 15˚C

increase in temperature. For example, the 1nA typical current at 25˚C would increase to 16nA at 85˚C.
