Test Circuit
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 specification 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 T
JMAX (maximum junction temperature), θJA
(junction to ambient thermal resistance), and T
A (ambient temperature). The maximum allowable power dissipation at any temperature is
PD
MAX = (TJMAX – TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041,
T
JMAX = 125°C, and the typical thermal resistance (θJA), when board mounted, is 326°C/W for the SOT-23 package.
Note 3.
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin. The machine model is a 200pF capacitor
discharged directly into each pin.
Note 4.
Typicals are at T
J = 25°C and represent most likely parametric norm.
Note 5.
Limits are 100% production tested at 25
°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control (SQL)
methods.
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)(65°C)(VR)]. VR/T is the VR temperature coefficient, 65°C is the temperature range from –40°C to the
reference point of 25
°C, and V
R is the reverse breakdown voltage. The total over temperature tolerance for the different grades follows:
A-grade:
±0.75% = ±0.1% ±100ppm/°C × 65°C
B-grade:
±0.85% = ±0.2% ±100ppm/°C × 65°C
C-grade:
±1.15% = ±0.5% ±100ppm/°C × 65°C
D-grade:
±1.98% = ±1.0% ±150ppm/°C × 65°C
Example: The A-grade LM4040-2.5 has an over temperature Reverse Breakdown Voltage tolerance of
±2.5 × 0.75% = ±19mV.
Note 7.
When V
OUT ≤ 1.6V, the LM4041-ADJ 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.
Specification for packaged product only.
