FEATURES
DESCRIPTION
The LM4030 is an ultra-high precision shunt voltage

High Output Voltage Accuracy 0.05%
reference, having exceptionally high initial accuracy
Low Temperature Coefficient 10 ppm/°C
(0.05%) and temperature stability (10ppm/°C). The
Extended Temperature Operation -40-125°C
LM4030 is available with fixed voltage options of 2.5V
and 4.096V. Despite the tiny SOT-23 package, the

Excellent Long-Term Stability, 40ppm
(75ppm) and long-term stability (40ppm) as well as
High Immunity to Board Stress Effects
immunity to board stress effects.
Capable of Handling 50 mA Transients
The LM4030 is designed to operate without an
Voltage Options 2.5V, 4.096V
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
APPLICATIONS
LM4030 can be powered off of virtually any supply
Data Acquisition/Signal path
and is a simple way to generate a highly accurate
system reference.
Test and Measurement
Automotive & Industrial
The LM4030 is available in three grades (A, B, and
C). The best grade devices (A) have an initial
