LM27 Electrical Characteristics (Continued)
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.
Note 2: When the input voltage (VI) at any pin exceeds the power supply (VI < GND or VI > V
+), the current at that pin should be limited to 5mA. The 20mA
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.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (junction to
ambient thermal resistance) and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PD =(TJmax–TA)/θJA or the number
given in the Absolute Maximum Ratings, whichever is lower. For this device, TJmax = 150C. For this device the typical thermal resistance (θJA) of the different
package types when board mounted follow:
Package Type
θ
JA
SOT23-5, MA05B
250C/W
Note 4: The human body model is a 100pF capacitor discharge through a 1.5k
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 6: Typicals are at TJ =TA = 25C and represent most likely parametric norm.
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
by 1.28mW when IOUT=3.2mA and VOUT=0.4V. With a thermal resistance of 250C/W, this power dissipation would cause an increase in the die temperature of about
0.32C due to self heating. Self heating is not included in the trip point accuracy specification.
Note 9: The 1A 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 15C
increase in temperature. For example, the 1nA typical current at 25C would increase to 16nA at 85C.

output.
the part number LM27CIM5-ZLN has T
US = 123C, and programmed as an active-high, push-pull undertemperature shutdown
output.
Active-high open-drain and active-low push-pull options are available, please contact National Semiconductor for more informa-
