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 W. Active output circuit provides a sharp turn−on characteristic, making these devices excellent replacements for Zener diodes in many applications.
