LM3411, LM3 Datasheet (National Semiconductor) - Precision Secondary Regulator/Driver

LM3411 - 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
