SC4431 Description
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. It achieves this by having seperate supply and output pins, allowing the output to sink current at voltages as low as 0.2V,...
