Shunt Voltage Reference  
General Description  
Features  
The LM4041 is a precision two-terminal shunt mode,  
bandgap voltage reference with a fixed reverse break-  
down voltage of 1.225V. Ideal for space-critical appli-  
cations, the LM4041 is offered in the subminiature 3-pin  
Ultra-Small 3-Pin SC70 Package  
0.1% (max) Initial Accuracy  
100ppm/°C (max) Temperature Coefficient  
Guaranteed over -40°C to +125°C Temperature  
Range  
SC70 surface-mount package (1.8mm 1.8mm), 50%  
smaller than comparable devices in SOT23 surface-  
mount packages (SOT23 versions are also available).  
Wide Operating Current Range: 60µA to 12mA  
Laser-trimmed resistors ensure precise initial accuracy.  
With a 100ppm/°C temperature coefficient, the device  
is offered in four grades of initial accuracy ranging from  
0.1% to 1%. The LM4041 has a 60µA to 12mA shunt  
current capability with low dynamic impedance, ensur-  
ing stable reverse-breakdown voltage accuracy over a  
wide range of operating temperatures and currents.

voltage. The total overtemperature tolerance for the different grades in the temperature range where maxΔT = +65°C is  
shown below:  
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  
The total overtemperature tolerance for the different grades in the extended temperature range where maxΔT = +100°C is  
shown below:  
A grade: ± 1.1% = ± 0.1% ± 100ppm/°C 100°C  
B grade: ± 1.2% = ± 0.2% ± 100ppm/°C 100°C  
C grade: ± 1.5% = ± 0.5% ± 100ppm/°C 100°C  
D grade: ± 2.5% = ± 1.0% ± 150ppm/°C 100°C  
Therefore, as an example, the A-grade LM4041-1.2 has an overtemperature reverse breakdown voltage tolerance of ± 2.5V  
x 0.75% = ± 19mV.

Detailed Description  
V
S
The LM4041 shunt references use the bandgap princi-  
ple to produce a stable, accurate voltage. The device  
behaves similarly to an ideal zener diode; a fixed volt-  
age of +1.225V is maintained across its output termi-  
nals when biased with 60µA to 12mA of reverse  
current. The LM4041 behaves similarly to a silicon  
diode when biased with forward currents up 10mA.

Applications Information  
The LM4041’s internal pass transistor is used to main-  
tain a constant output voltage (V ) by sinking the  
SHUNT  
necessary amount of current across a source resistor.  
The source resistance (R ) is determined from the load  
S
current (I  
SHUNT  
) range, supply voltage (V ) variations,  
, and desired quiescent current.

Output Capacitance  
The LM4041 does not require an external capacitor for  
frequency stability and is stable for any output capaci-

Therefore, the value of R is bounded by the following

Temperature Performance  
The LM4041 typically exhibits an output voltage tem-  
perature coefficient within ± 15ppm/°C. The polarity of  
the temperature coefficient may be different from one  
device to another; some may have positive coefficients,  
and others may have negative coefficients.

+125°C, the part operates at 159.56°C, thereby  
High Temperature Operation  
The maximum junction temperature of the LM4041 is  
+150°C. The maximum operating temperature for the  
LM4041_E_ is +125°C. At a maximum load current of  
15mA and a maximum output voltage of 5V, the part  
will dissipate 75mW of power. The power dissipation  
limits of the 3-pin SC70 call for a derating value of  
2.17mW/°C above +70°C and thus for 75mW of power  
dissipation, the part will selfheat to 35.56°C above  
ambient temperature. If the ambient temperature is  
exceeding the maximum junction temperature value of  
+150°C. For high-temperature operation, care must be  
taken to ensure the combination of ambient tempera-  
ture, output power dissipation, and package thermal  
resistance does not conspire to raise the device tem-  
perature beyond that listed in the Absolute Maximum  
Ratings. Either reduce the output load current or the  
ambient temperature to keep the part within the limits.
