www.DataSheet4U.com AT431 Preliminary Product Information 1.24V low-Voltage Adjustable Precision Shunt Regulator Features ․Low-Voltage Operation: Down to 1.24V ․1% Reference-Voltage Tolerance ․Adjustable Output Voltage, Vo=Vref to 12V ․Low Operational Cathode Current….50μA ․0.25Ω Typical Output Impedance ․SOT-23 and TO-92 Packages Description 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.
