LM4040BIM3-5.0 - MICROCHIP TECHNOLOGY

LM4040-N/LM4040Q-N

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 capaci-

tor while ensuring stability with any capacitive load, thus

making the LM4040 easy to use. Further reducing design ef-

fort 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 ±[(ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VR temperature coefficient, maxΔT 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 maxΔT = 65°C is shown below:

A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C

B-grade: ±0.85% = ±0.2% ±100 ppm/°C × 65°C

C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C

D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C

E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C

The total over-temperature tolerance for the different grades in the exteded temperature range where max ΔT = 100 °C is shown below:

C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C

D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C

E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C

Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature Reverse Breakdown Voltage tolerance of ±2.5V × 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.

Note 9: Peak Reflow Temperatures for Surface Mount devices are defined in “Absolute Maximum Ratings for Soldering”, Literature Number: SNOA549C

Applications Information

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

LM4040-2.048 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.

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. 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.

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.
