7 / 22 page ![]() DC Electrical Characteristics (Continued) Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Note 2 Operating Ratings indicate conditions for which the device is intended to be functional These ratings do not guarantee specific performance limits however 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 3 All voltages are measured with respect to GND unless otherwise specified Note 4 See AN450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ or the section titled ‘‘Surface Mount’’ found in any current Linear Data Book for other methods of soldering surface mount devices Note 5 The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX HJA and the ambient temperature TA The maximum allowable power dissipation at any temperature is PD e (TJMAX b TA) HJA or the number given in the Absolute Maximum Ratings whichever is lower For this device TJMAX e 150 C and the typical thermal resistance (HJA) when board mounted is 61 CW for the LMF90CCN and CIN 134 CW for the LMF90CCWM and CWIM and 59 CW for the LMF90CCJ CIJ and CMJ Note 6 Human body model 100 pF discharged through a 15 kX resistor Note 7 Typicals are at TJ e 25 C and represent the most likely parametric norm Note 8 Tested Limits are guaranteed and 100% tested Note 9 Design Limits are guaranteed but not 100% tested Note 10 When the input voltage (VIN) at any pin exceeds the power supplies (VIN k V b or VIN l V a ) the current at that pin should be limited to 5 mA The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four 7 |
