SC4431 Datasheet (Semtech Corporation) - SHUNT REGULATOR WITH OPEN COLLECTOR OR OUTPUT

SC4431, SHUNT REGULATOR WITH OPEN COLLECTOR OR OUTPUT

The SC4431 is a four terminal device for regulating an isolated power supply with very low output voltage.

It is intended to be used as a replacement for three terminal shunt regulators such as SC431L where the output voltage is too low for them to function in conjunction with an opto-isolator.
