The LM2675 series of regulators are monolithic integrated DC-DC converter circuits built with an LMDMOS process. These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1-A load current with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, and 12 V, and an adjustable output version.
