Improved Precision Micropower Shunt Voltage  
Reference with Multiple Reverse Breakdown Voltages  
General Description  
Features  
The LM4040 is a precision two-terminal shunt mode,  
bandgap voltage reference available in fixed reverse  
breakdown voltages of 2.048V, 2.500V, 3.000V, 3.3V,  
4.096V, and 5.000V. Ideal for space-critical applica-  
tions, the LM4040 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 15mA  
♦ Low 28µV  
Output Noise (10Hz to 10kHz)  
RMS  
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 LM4040 has a 60µA to 15mA shunt  
current capability with low dynamic impedance, ensur-  
ing stable reverse breakdown voltage accuracy over a  
wide range of operating temperatures and currents.  
♦ 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V  
Fixed Reverse Breakdown Voltages  
♦ No Output Capacitors Required  
♦ Tolerates Capacitive Loads  
The LM4040 does not require an external stabilizing  
capacitor while ensuring stability with any capacitive  
load.  
The LM4040 is guaranteed over the temperature range  
of -40°C to +125°C.
