It features exceptionally high initial accuracy (0.05%), temperature stability (10ppm/°C), and 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). It also has immunity to board stress effects.

The LM4030 is designed to operate without an external capacitor, but any capacitor up to 10µF may be used. Worth noting is that it can be powered off to 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. It offers 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.
