SOT-23 Ultra-High Precision Shunt Voltage Reference
General Description
The LM4030 is an ultra-high precision shunt voltage refer-
ence, 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 hys-
teresis (75ppm) and long-term stability (40ppm) as well as
immunity to board stress effects.
The LM4030 is designed to operate without an external ca-
pacitor, 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
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.
High output voltage accuracy 0.05%
Low temperature coefficient 10 ppm/°C
Extended temperature operation -40-125°C
