FEATURES  
DESCRIPTION  
Ideal for space critical applications, the LM4050-N

•
•
•
•
Small Package: SOT-23  
precision voltage reference is available in the sub-  
miniature (3 mm x 1.3 mm) SOT-23 surface-mount  
package. The LM4050-N design eliminates the need  
for an external stabilizing capacitor while ensuring  
stability with any capacitive load, thus making the  
LM4050-N easy to use. Further reducing design effort  
is the availability of several fixed reverse breakdown  
voltages: 2.048V, 2.500V, 4.096V, 5.000V, 8.192V,  
and 10.000V. The minimum operating current  
increases from 60 μA for the LM4050-N-2.0 to 100  
μA for the LM4050-N-10.0. All versions have a  
maximum operating current of 15 mA.  
No Output Capacitor Required  
Tolerates Capacitive Loads  
Fixed Reverse Breakdown Voltages of 2.048V,  
2.500V, 4.096V, 5.000V, 8.192V, and 10.000V

The LM4050-N 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
