Adjustable Precision Shunt Regulator Features - - - - - - - - Precise Reference Voltage to 2.500V Guaranteed 0.5% or 1% Reference Voltage Tolerance .. General Description The APL1431 is a 3-terminal adjustable voltage reference with specified thermal stability over applicable mercial temperature ranges. Output voltage may be set to any value between Vref (2.5 V) and 20 V with two external resistors (see Figure 2). When used with an photocoupler, the APL1431 is an ideal voltage reference in isolated feedback circuits for 2.5V to 12V switching-mode power supplies. This device has a typical output impedance of 0.1Ω. Active output circuitry provides a very sharp...
