The HA17431H 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, which have a VKA max of 36 volts. Features •.
• The reference voltage provide 2.500 V ±1% at Ta = 25°C
• The reference voltage has a low temperature coefficient
• The MPAK-5V (5 pin), MPAKV (3 pin) and UPAKV miniature packages are optimal for use on high mounting
