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, 12 V, and an adjustable output version.</span></span><br style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255);"/><br style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255);"/><span style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255); vertical-align: inherit;"><span style="box-sizing: border-box; vertical-align: inherit;">Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation and a fixed frequency oscillator.</span></span><br style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255);"/><br style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255);"/><span style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; white-space: normal; background-color: rgb(255, 255, 255); vertical-align: inherit;"><span style="box-sizing: border-box; vertical-align: inherit;">The LM2675 series operates at a switching frequency of 260 kHz, thus allowing smaller-sized filter components than what would be needed with lower frequency switching regulators.
