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°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°C to 105°C. The AS431C is available in TO-92, SOT-23-5 and SOT-89 packages.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
