PRODUCT DESCRIPTION
The TL431 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate 1% bandgap reference. TL431 acts as an
open-loop error amplifier with a 2.5V temperature compensation reference. The TL431 thermal stability, wide operating current
(150mA) and temperature range (0
°C to 105°C) makes it suitable for all variety of application that are looking for a low cost solution
with high performance.
The output voltage may be adjusted to any value between VREF and 36 volts with two external resistors. The TL431 is operating in full
industrial temperature range of 0°C to 105°C. The TL431 is available in TO-92, SO-8, SOT-89 and SOT23-5 packages.
