TL431K
Adjustable Shunt Regulator
RoHS Compliant Product
Description
The TL431K series are three-terminal adjustable regulators
with guaranteed thermal stability over applicable temperature
ranges. The output voltage may be set to any value between _S
VREF (approximately 2.495V) and 36V with two extermal
resistors. In provides very wide applications, including shunt
regulator, series regulator, switching regulator, voltage
reference and others.
