Texas Instruments LM2575-N
The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. The LM2575 series offers a high-efficiency replacement for popular three-terminal linear regulators.| Part No. | LM2575-N |
