Alfa-MOS Technology AF431N 36V High Voltage Adjustable Precision Shunt Regulators General Description The AF431N is high-voltage three-terminal adjustable voltage references, with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (2.5V) and 36V with two external resistors. These devices have a typical output impedance of 0.25Ω. Active output circuitry provides a very sharp turn-on characteristic, making the AF431N excellent replacements for low-voltage Zener diodes in many applications, including onboard regulation and adjustable power supplies. Features Low Output Noise Adjustable Output Voltage, VO = Vref to 36 V Low Operational Cathode Current 0.
