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 ±1% accuracy in the V versions, which have a VKA max of 16 volts.

Features

• The V versions provide 2.500 V ±1% at Ta = 25°C

• The reference voltage has a low temperature coefficient

• The UPAKV miniature packages are optimal for use on high mounting density circuit boards
