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 V
REF
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
.
