Product Summary

The lm3411am5x-3.3 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 lm3411am5x-3.3 circuitry includes an internally compensated op amp, a bandgap reference, NPN output transistor, and voltage setting resistors. The applications of the lm3411am5x-3.3 are (1)Secondary controller for isolated DC/DC PWM switching regulators systems; (2)Use with LDO regulator for high-precision fixed output regulators; (3)Precision monitoring applications; (4)Use with many types of regulators to increase precision and improve performance.
