50ppm/°C Precision Micropower Shunt Voltage  
References with Multiple Reverse Breakdown Voltages  
General Description  
Features  
50ppm/°C (max) Temperature Coefficient  
The LM4050/LM4051 are precision two-terminal, shunt-  
mode, bandgap voltage references available in fixed  
reverse breakdown voltages of 1.225V, 2.048V, 2.500V,  
3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-criti-  
cal applications, the LM4050/LM4051 are offered in the  
subminiature 3-pin SC70 surface-mount packages  
(1.8mm x 1.8mm), 50% smaller than comparable  
devices in SOT23 surface-mount package (SOT23 ver-  
sions are also available).  
Guaranteed over the -40°C to +125°C  
Temperature Range  
Ultra-Small 3-Pin SC70 Package  
0.1% (max) Initial Accuracy  
Wide Operating Current Range: 60µA to 15mA  
Low 28µV  
Output Noise (10Hz to 10kHz)  
RMS  
Laser-trimmed resistors ensure excellent initial  
accuracy. With a 50ppm/°C temperature coefficient,  
these devices are offered in three grades of initial accu-  
racy ranging from 0.1% to 0.5%. The LM4050/LM4051  
have a 60µA to 15mA shunt-current capability with low  
dynamic impedance, ensuring stable reverse break-  
down voltage accuracy over a wide range of operating  
temperatures and currents. The LM4050/LM4051 do  
not require an external stabilizing capacitor while  
ensuring stability with any capacitive loads.  
1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and  
5.000V Fixed Reverse Breakdown Voltages
