SHUNT REGULATOR WITH OPEN COLLECTOR OR OUTPUT

Description The SC4431 is a four terminal device for regulating an isolated power supply with output voltages down to 1.5V. 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 the device to function in conjunction
