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.

The HA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode power supplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be easily constructed on the supply side.

Features

• 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(5-pin), MPAK(3-pin) and UPAK miniature packages are optimal for use on high mounting density circuit boards

• Car use is provided
