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 鹵1% accuracy in the V versions, which have a V
KA
max of 16 volts.
Features
鈥?/div>
The V versions provide 2.500 V 鹵1% at Ta = 25擄C
鈥?/div>
The reference voltage has a low temperature coefficient
鈥?/div>
The UPAKV miniature packages are optimal for use on high mounting density circuit boards
