HA17431

• The V versions provide 2.500 V ±1% at Ta = 25°C
• The HA17431VLP includes a photocoupler bypass resistor (2 kΩ)
• The reference voltage has a low temperature coefficient
• The MPAK-5 and UPAK miniature packages are optimal for use on high mounting density circuitboards
• A wide operating temperature range (40 to +85°C) is provided by the TO-92, TO-92MOD, and FP-8Dpackage versions

The HA17431 series is a family of voltage referenced shunt regulators. The main application of theseproducts is in voltage regulators that provide a variable output voltage. The HA17431 series products areprovided in a wide range of packages; TO-92 and TO-92MOD insertion mounting packages and MPAK-5,UPAK, and FP-8D surface mounting packages are available. The on-chip high-precision reference voltagesource can provide ±1% accuracy in the V versions, which have a VKA max of 16 volts. TheHA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode powersupplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can beeasily constructed on the supply side.
