HA17431HLTP - Renesas

HA17431HLTP Shunt Regulator

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 • Th.

Features
