NSC LM4040DIM3-3.0 Precision micropower shunt voltage reference Datasheet

LM4040
Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4040 precision
voltage reference is available in the sub-miniature SC70 and
SOT-23 surface-mount package. The LM4040’s advanced
design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus
making the LM4040 easy to use. Further reducing design
effort is the availability of several fixed reverse breakdown
voltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V,
and 10.000V. The minimum operating current increases from
60 µA for the LM4040-2.5 to 100 µA for the LM4040-10.0. All
versions have a maximum operating current of 15 mA.
The LM4040 utilizes fuse and zener-zap reverse breakdown
voltage trim during wafer sort to ensure that the prime parts
have an accuracy of better than ± 0.1% (A grade) at 25˚C.
Bandgap reference temperature drift curvature correction
and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.
Also available is the LM4041 with two reverse breakdown
voltage versions: adjustable and 1.2V. Please see the
LM4041 data sheet.

Electrical Characteristics(Notes)
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 LM4040, TJmax = 125˚C, and the typical thermal resistance (θJA), when board mounted,
is 326˚C/W for the SOT-23 package, and 180˚C/W with 0.4" lead length and 170˚C/W with 0.125" lead length for the TO-92 package and 415˚C/W for the SC70
Package.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4: Typicals are at TJ = 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 (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
± [(∆VR/∆T)(max∆T)(VR)]. Where, ∆VR/∆T is the VR temperature coefficient, max∆T is the maximum difference in temperature from the reference point of 25˚C to
T MIN or TMAX, and VR is the reverse breakdown voltage. The total over-temperature tolerance for the different grades in the industrial temperature range where
max∆T = 65˚C is shown below:
A-grade: ± 0.75% = ± 0.1% ± 100 ppm/˚C x 65˚C
B-grade: ± 0.85% = ± 0.2% ± 100 ppm/˚C x 65˚C
C-grade: ± 1.15% = ± 0.5% ± 100 ppm/˚C x 65˚C
D-grade: ± 1.98% = ± 1.0% ± 150 ppm/˚C x 65˚C
E-grade: ± 2.98% = ± 2.0% ± 150 ppm/˚C x 65˚C
The total over-temperature tolerance for the different grades in the exteded temperature range where max ∆T = 100 ˚C is shown below:
C-grade: ± 1.5% = ± 0.5% ± 100 ppm/˚C x 100˚C
D-grade: ± 2.5% = ± 1.0% ± 150 ppm/˚C x 100˚C
E-grade: ± 3.5% = ± 2.0% ± 150 ppm/˚C x 100˚C
Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature Reverse Breakdown Voltage tolerance of ± 2.5V x 0.75% = ± 19 mV.
Note 7: Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change must be taken into
account separately.
Note 8: Thermal hysteresis is defined as the difference in voltage measured at +25˚C after cycling to temperature -40˚C and the 25˚C measurement after cycling
to temperature +125˚C.

The LM4040 is a precision micro-power curvature-corrected
bandgap shunt voltage reference. For space critical applications, the LM4040 is available in the sub-miniature SOT-23
and SC70 surface-mount package. The LM4040 has been
designed for stable operation without the need of an external
capacitor connected between the “+” pin and the “−” pin. If,
however, a bypass capacitor is used, the LM4040 remains
stable. Reducing design effort is the availability of several
fixed reverse breakdown voltages: 2.048V, 2.500V, 3.000V,
4.096V, 5.000V, 6.000, 8.192V, and 10.000V. The minimum
operating current increases from 60 µA for the LM40402.048 and LM4040-2.5 to 100 µA for the LM4040-10.0. All
versions have a maximum operating current of 15 mA.
LM4040s in the SOT-23 packages have a parasitic Schottky
diode between pin 2 (−) and pin 3 (Die attach interface
contact). Therefore, pin 3 of the SOT-23 package must be
left floating or connected to pin 2.
LM4040s in the SC70 have a parasitic Schottky diode between pin 1 (−) and pin 2 (Die attach interface contact).
Therefore, pin 2 must be left floating or connected to pin1.
In a conventional shunt regulator application (Figure 1) , an
external series resistor (RS) is connected between the supply voltage and the LM4040. RS determines the current that
flows through the load (IL) and the LM4040 (IQ). Since load
current and supply voltage may vary, RS should be small
enough to supply at least the minimum acceptable IQ to the
LM4040 even when the supply voltage is at its minimum and
the load current is at its maximum value. When the supply
voltage is at its maximum and IL is at its minimum, RS should
be large enough so that the current flowing through the
LM4040 is less than 15 mA.
RS is determined by the supply voltage, (VS), the load and
operating current, (IL and IQ), and the LM4040’s reverse
breakdown voltage, VR.
The 4.096V version allows single +5V 12-bit ADCs or DACs
to operate with an LSB equal to 1 mV. For 12-bit ADCs or
DACs that operate on supplies of 10V or greater, the 8.192V
version gives 2 mV per LSB.
The typical thermal hysteresis specification is defined as the
change in +25˚C voltage measured after thermal cycling.

LM4040
The device is thermal cycled to temperature -40˚C and then
measured at 25˚C. Next the device is thermal cycled to
temperature +125˚C and again measured at 25˚C. The resulting VOUT delta shift between the 25˚C measurements is
thermal hysteresis. Thermal hysteresis is common in precision references and is induced by thermal-mechanical package stress. Changes in environmental storage temperature,
operating temperature and board mounting temperature are
all factors that can contribute to thermal hysteresis.
