LM4051-ADJ (Adjustable)
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: 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 PDmax =(TJmax TA)/θJA or the
number given in the Absolute Maximum Ratings, whichever is lower. For the LM4051, TJmax = 125C, and the typical thermal resistance (θJA), when board mounted,
is 280C/W for the SOT-23 package.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4: Typicals are at TJ = 25C and represent most likely parametric norm.
Note 5: Limits are 100% production tested at 25C. Limits over temperature are guaranteed through correlation using Statistical Quality Control (SQC) methods.
The limits are used to calculate National’s AOQL.
Note 6: The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance
±[(
V R/T)(max T)(VR)]. Where, VR/T is the VR temperature coefficient, maxT is the maximum difference in temperature from the reference point of 25 C to
T MAX or TMIN, and VR is the reverse breakdown voltage. The total over-temperature tolerance for the different grades in the industrial temperature range where
max
T=65C is shown below:
A-grade: ±0.425% = ±0.1% ±50 ppm/C x 65C
B-grade: ±0.525% = ±0.2% ±50 ppm/C x 65C
C-grade: ±0.825% = ±0.5% ±50 ppm/C x 65C
Therefore, as an example, the A-grade LM4051-1.2 has an over-temperature Reverse Breakdown Voltage tolerance of ±1.2V x 0.425% = ±5.2 mV.
Note 7: When VOUT ≤ 1.6V, the LM4051-ADJ in the SOT-23 package must operate at reduced IR. This is caused by the series resistance of the die attach between
the die (-) output and the package (-) output pin. See the Output Saturation curve in the Typical Performance Characteristics section.
Note 8: Reference voltage and temperature coefficient will change with output voltage. See Typical Performance Characteristics curves.
Note 9: Long term stability is VR @ 25C measured during 1000 hrs.
Note 10: Thermal hysteresis is defined as the difference in voltage measured at +25C after cycling to temperature -40C and the 25C measurement after cycling
to temperature +125C.
