PRODUCT DESCRIPTION
The SPX431C is a 3-Terminal Adjustable Shunt Voltage Regulator providing a highly accurate bandgap reference. SPX431C acts as
an open-loop error amplifier with a 2.5V temperature compensation reference. The SPX431C thermal stability, wide operating current
(150mA) and temperature range (105°C) makes it suitable for all variety of applications that are looking for a low cost solution with
high performance.
The output voltage may be adjusted to any value between V_REF and 36V with 2 external resistors. The SPX431C is operating in full
industrial temperature range of 0°C to 105°C. The SPX431C is available in TO-92, SOT-23-5 and SOT-89 packages.
