LM4030 SOT-23 Ultra-High Precision Shunt Voltage Reference
General 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 SOT23 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 10F may be used. The LM4030 can be powered off as little as 120A (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 guaranteed 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.
