PRODUCT DESCRIPTION
The SPX431L is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate bandgap reference. SPX431L acts as an
open-loop error amplifier with a 2.5V temperature compensation reference. The SPX431L thermal stability, wide operating current
(100mA) and temperature range (0擄C to 105擄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 20V with 2 external resistors. The SPX431L is operating in full
industrial temperature range of 0擄C to 105擄C. The SPX431L is available in TO-92, SOT-89, SOT-23-3 and SO-8 packages.
