PRODUCT DESCRIPTION
The SPX431 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate 0.5% bandgap reference. SPX431 acts as an
open-loop error amplifier with a 2.5V temperature compensation reference. The SPX431 thermal stability, wide operating current
(150mA) and temperature range (0
°
C to
105
°
C) makes it suitable for all variety of application that are looking for a low cost solution
with high performance.
SPX431 tolerance of 0.5% 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 manufactures assembly line and contribute a significant cost
savings.
The output voltage may be adjusted to any value between V
REF
and 36 volts with two external resistors. The SPX431 is operating an
extended temperature range of 0°C to 105°C. The SPX431 is available in TO-92, SO-8, SOT-89, and SOT-23-5 packages
.
