Product Summary

The LM334M is a 3-terminal adjustable current source. Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM334M is true floating current sources with no separate power supply connections. The applications for the LM334M include bias networks, surge protection, low power reference, ramp generation, LED driver, and temperature sensing.
