GENERAL DESCRIPTION
The SPX1431 is a 3-terminal adjustable shunt
voltage regulator providing a highly accurate
bandgap reference. The SPX1431 acts as an
open-loop error amplifier with a 2.5V
temperature compensation reference. The
SPX1431's thermal stability, wide operating
current (150mA) and temperature range
(-55°C to 125°C) makes it suitable for a
variety of applications that require a low cost,
high performance solution. SPX1431 tolerance
of 0.4% is proven to be sufficient to overcome
all of the other errors in the system to virtually
eliminate the need for trimming in the power
supply manufacturer's assembly lines and
contributes a significant cost savings.
The output voltage may be adjusted to any
value between VREF and 36 volts with two
external resistors. The SPX1431 is available in
SOIC-8 and SOT-89-3 packages.
