LM3411 Datasheet (Texas Instruments) - Precision Secondary Regulator/Driver

LM3411, Precision Secondary Regulator/Driver

The LM3411 is a low-power fixed-voltage (3.3 V or 5 V) precision shunt regulator designed specifically for driving an optoisolator to provide feedback isolation in a switching regulator.

The LM3411 circuitry includes an internally compensated operational amplifier, a bandgap reference, NPN output tr
