The LM4050QML precision voltage reference is
available in a 10-Lead Ceramic CLGA package. The
LM4050QML's design eliminates the need for an
external stabilizing capacitor while ensuring stability
with a capacitive load, thus making the LM4050QML
easy to use. The LM4050-2.5QML has a 60 μA
minimum and 15 mA maximum operating current.
The LM4050-5.0QML has a 74 μA minimum and
15 mA maximum operating current.
The LM4050QML 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% 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.
The LM4050QML operates over the temperature
range of -55°C to +125°C.

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 ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
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
LM4050QML, TJmax = 125°C, and the typical thermal resistance (θJA), when board mounted, is 214°C/W for the 10-Lead Ceramic CLGA
package.
The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.

Functional Block Diagram
APPLICATIONS INFORMATION
The LM4050QML is a precision micro-power curvature-corrected bandgap shunt voltage reference. The
LM4050QML is available in the 10-Lead Ceramic CLGA package. The LM4050QML 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 LM4050QML remains stable. The LM4050-2.5QML has a 60 μA
minimum and 15 mA maximum operating current. The LM4050-5.0QML has a 74 μA minimum and 15 mA
maximum operating current.
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 -55°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 12) , an external series resistor (RS) is connected between
the supply voltage and the LM4050QML. RS determines the current that flows through the load (IL) and the
LM4050QML (IQ). Since load current and supply voltage may vary, RS should be small enough to supply at least
the maximum ensured IRMIN (spec. table) to the LM4050QML 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 LM4050QML is less than 15 mA.
RS is determined by the supply voltage, (VS), the load and operating current, (IL and IQ), and the LM4050QML's
reverse breakdown voltage, VR.

Radiation Environments
Careful consideration should be given to environmental conditions when using a product in a radiation
environment.
TOTAL IONIZING DOSE
Radiation hardness assured (RHA) products are those part numbers with a total ionizing dose (TID) level
specified in the Ordering Information table on the front page. Testing and qualification of these products is done
on a wafer level according to MIL-STD-883, Test Method 1019. Wafer level TID data is available with lot
shipments.
Testing and qualification is performed at the 30, 50 and 100 krad TID levels at a dose rate of 10 mrad/s, using a
1.5X overtest at each TID level. For the 30 krad level units are tested to 50 krad, for 50 krad units are tested to
80 krad and for 100 krad units are tested to 150 krad, with all parameters remaining inside the post irradiation
test limits.

Figure 14. The LM4050QML as a power supply and reference
The LM4050QML is a good choice as a power regulator for the DAC121S101QML or ADC128S102QML. The
minimum resistor value in the circuit of Figure 13 or Figure 14 should be chosen such that the maximum current
through the LM4050QML does not exceed its 15 mA rating. The conditions for maximum current include the input
voltage at its maximum, the LM4050QML voltage at its minimum, the resistor value at its minimum due to
tolerance, and the DAC121S101QML or ADC128S102QML draws zero current. The maximum resistor value
must allow the LM4050QML to draw more than its minimum current for regulation plus the maximum
DAC121S101QML or ADC128S102QML current in full operation. The conditions for minimum current include the
input voltage at its minimum, the LM4050QML voltage at its maximum, the resistor value at its maximum due to
tolerance, and the DAC121S101QML or ADC128S102QML draws its maximum current. These conditions can be
summarized as
R(min) = ( VIN(max) − VZ(min) / (IA(min) + IZ(max)
(2)
R(max) = ( VIN(min) − VZ(max) / (IA(max) + IZ(min)
(3)
and
where VZ(min) and VZ(max) are the nominal LM4050QML output voltages ± the LM4050QML output tolerance
over temperature, IZ(max) is the maximum allowable current through the LM4050QML, IZ(min) is the minimum
current required by the LM4050QML for proper regulation, IA(max) is the maximum DAC121S101QML or
ADC128S102QML supply current, and IA(min) is the minimum DAC121S101QML or ADC128S102QML supply
current.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
