Product Summary

The ha17431fpa is temperature-compensated variable shunt regulator. The main application of the ha17431fpa 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 ha17431fpa, 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.
