Note 1: The package code MA05B is internal to National Semiconductor Corporation and indicates a specific version of the SOT-23 package and associated me-
chanical drawings.
Note 2: The suffix “I” indicates the junction temperature range for operation is the industrial temperature range, −40 to +125˚C. The suffix “M5” indicates the die is
packaged in the 5-lead SOT-23 package. The suffix “X” indicates the devices will be supplied in blocks of 3k units as opposed to blocks of 250 units.
Note 3: Because the entire part number does not fit on the SOT-23 package, the SOT-23 package is marked with this code instead of the part number.
Note 4: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 5: The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (T
perature, T
junction temperature, 150˚C, for T
dissipated at higher ambient temperatures. The Absolute Maximum power dissipation can be increased by 4 mW for each ˚C below 50˚C ambient. It must be derated
by 4 mW for each ˚C above 50˚C ambient. A
ing enables the safe dissipation of more power. The LM3490 actively limits its junction temperature to about 150˚C.
Note 6: Times shown are dwell times. Temperatures shown are dwell temperatures. For detailed information on soldering plastic small-outline packages, refer to the
Packaging Databook available from National Semiconductor Corporation.
Note 7: For testing purposes, ESD was applied using the human-body model, a 100 pF capacitor discharged through a 1.5 k
Note 8: As with the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 300 mW rating
appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125˚C, for T
