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.

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.
