PRODUCT DESCRIPTION
The ALPHA Semiconductor 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 pensation 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 maybe adjusted to any value between VREF and 36V with 2 external resistors. The AS431C is operating in lull industrial temperature range of 0°C to 105°C. The AS431C is available in TO-92 and SOT-89 packages.
