1.24V Low-Voltage Adjustable Precision Shunt Regulator

The AT431 is low-voltage three-terminal adjustable Voltage Reference with specified thermal stability over applicable commercial temperature ranges. Output voltage may be set to any value between Vref (1.24V) and 12V with two external resistors (see Figure 2). When used with an Optocoupler the AT431 is ideal Voltage Reference in isolated feedback circuits for 1.8V to 12 V switching-mode power supplies. This device has typical output impedance of 0.20. Active output circuitry provides a very sharp turn-on characteristic, making the AT431 excellent replacements for low-voltage zener Diodes in many applications, including onboard regulation and adjustable power supplies.
