HA17431 Series Shunt Regulator ADE-204-049A (Z) Rev.1 Sep. 2002 Description The HA17431 series is temperature-compensated variable shunt regulators. The main application of these products is in voltage regulators that provide a variable output voltage. The on-chip high-precision reference voltage source can provide ±1% accuracy in the V versions, which have a VKA max of 16 volts. The HA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode power supplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be easily constructed on the supply side. Features • The V versions provide 2.
