FEATURES  
DESCRIPTION  
The LM4030 is an ultra-high precision shunt voltage  
reference, having exceptionally high initial accuracy  
(0.05%) and temperature stability (10ppm/°C). The  
LM4030 is available with fixed voltage options of 2.5V  
and 4.096V. Despite the tiny SOT-23 package, the  
LM4030 exhibits excellent thermal hysteresis  
(75ppm) and long-term stability (40ppm) as well as  
immunity to board stress effects.

High Output Voltage Accuracy 0.05%  
Low Temperature Coefficient 10 ppm/°C  
Extended Temperature Operation -40-125°C  
Excellent Thermal Hysteresis, 75ppm  
Excellent Long-Term Stability, 40ppm  
High Immunity to Board Stress Effects  
Capable of Handling 50 mA Transients  
Voltage Options 2.5V, 4.096V  
The LM4030 is designed to operate without an  
external capacitor, but any capacitor up to 10µF may  
be used. The LM4030 can be powered off as little as  
120µA (max) but is capable of shunting up to 30mA  
continuously. As with any shunt reference, the  
LM4030 can be powered off of virtually any supply  
and is a simple way to generate a highly accurate  
system reference.

Communications  
The LM4030 is available in three grades (A, B, and  
C). The best grade devices (A) have an initial  
accuracy of 0.05% with ensured temperature  
coefficient of 10 ppm/°C or less, while the lowest  
grade parts (C) have an initial accuracy of 0.15% and  
a temperature coefficient of 30 ppm/°C.
