Product Summary
The HA17431UA-TL-E is a temperature-compensated variable shunt regulator. The main application of the HA17431UA-TL-E 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-5V package, is designed for use in switching mode power supplies. The HA17431UA-TL-E provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be easily constructed on the supply side.
