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.
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.
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.
