LM3411, LM3, Precision Secondary Regulator/Driver
The LM3411 is a low power fixed-voltage (3.3V or 5.0V) precision shunt regulator designed specifically for driving an optoisolator to provide feedback isolation in a switching regulator.
The LM3411 circuitry includes an internally compensated op amp, a bandgap reference, NPN output transistor, and v
