Programmable Shunt Regulator
LM431A, LM431B, LM431C
Description The LM431A/LM431B/LM431C are three−terminal output
adjustable regulators with thermal stability over the full operating temperature range. The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic outp...
