HA17431H Series Shunt Regulator ADE-204-070A (Z) Rev.1 Sep. 2002 Description 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-5 (5 pin), MPAK (3 pin) and UPAK miniature packages are optimal for use on high mounting density circuit boards Block Diagram K REF + − 2.500 V A HA17431H Series Application Circuit Example Switching power supply secondary-side error amplification circuit Vout R R1 + K – REF R2 A GND HA17431H Series Ordering Information Item Industrial use HA17431HLTP Package Temp.
