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 V (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications.
