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 condi-
tions.
Note 2:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
Jmax
(maximum junction temperature),
θ
JA
(junction to am-
bient thermal resistance), and T
A
(ambient temperature). The maximum allowable power dissipation at any temperature is PD
max
= (T
Jmax
T
A
)/
θ
JA
or the number
given in the Absolute Maximum Ratings, whichever is lower. For the LM4051, T
Jmax
= 125C, and the typical thermal resistance (
θ
JA
), when board mounted, is
280C/W for the SSOT-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 di-
rectly into each pin.
Note 4:
Typicals are at T
J
= 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)(V
R
)]. Where,
V
/
T is the V
temperature coefficient, max
T is the maximum difference in temperature from the reference point of 25 C to
T
MAX
or T
, and V
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:
±
0.522% =
±
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 V
≤
1.6V, the LM4051-ADJ in the SSOT-23 package must operate at reduced I
. 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 V
R
@
25C measured during 1000 hrs.
Note 10:
Thermal hysteresis is defined as the changes in 25C output voltage before and after cycling the device from 40C or +125C.
