Note 1: 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 2: All voltages are with respect to the potential at the GND pin.
Note 3: Additional information on pad temperature can be found in National Semiconductor Application Note (AN-1112).
Note 4: The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using the formula:
Where T
Absolute Maximum Ratings results from substituting the Absolute Maximum junction temperature, 150°C, for T
can be dissipated safely at ambient temperatures below 70°C . Less power can be dissipated safely at ambient temperatures above 70°C. The Absolute Maximum
power dissipation can be increased by 4.5mW for each degree below 70°C, and it must be derated by 4.5mW for each degree above 70°C.
Note 5: The human body model is 100pF discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor discharged directly into
each pin.
Note 6: Like the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 250mW rating
appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125°C, for T
into (1) above. More power can be dissipated at ambient temperatures below 70°C . Less power can be dissipated at ambient temperatures above 70°C. The
maximum power dissipation for operation can be increased by 4.5mW for each degree below 70°C, and it must be derated by 4.5mW for each degree above 70°
C.
Note 7: All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
Statistical Quality Control (SQC) methods. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations
and applying statistical process control.
Note 8: The target output voltage, which is labeled V
Note 9: The output voltage changes slightly with line voltage. An increase in the line voltage results in a slight increase in the output voltage and vice versa.
Note 10: The output voltage changes slightly with load current. An increase in the load current results in a slight decrease in the output voltage and vice versa.
Tested limit applies to Vout 's of 2.5V and greater.
Note 11: Dropout voltage is the input-to-output voltage difference at which the output voltage is 100mV below its nominal value.
Note 12: Turn-on time is that between the enable input just exceeding V
Note 13: Range of capacitor values for which the device will remain stable. This electrical specification is guaranteed by design.
Note 14: Range of capacitor ESR values for which the device will remain stable. This electrical specification is guaranteed by design.
