LM431A Overview
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 output impedance of 0.2.
