PRODUCT DESCRIPTION
The AS431C is a 3-Terminal Adjustable Shunt Voltage Regulator providing a highly accurate bandgap reference. AS431C acts as an
open-loop error amplifier with a 2.5V temperature compensation reference. The AS431C thermal stability, wide operating current
(150mA) and temperature range (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 36V with 2 external resistors. The AS431C is operating in full
industrial temperature range of 0擄C to 105擄C. The AS431C is available in TO-92, SOT-23-5 and SOT-89 packages.
