LM257x SIMPLE SWITCHER® Voltage Regulators

Texas Instruments LM257x SIMPLE SWITCHER® Step-Down Voltage Regulators are high-efficiency devices ranging from 0.5A to 3A output current. TI LM2574 and LM2574HV SIMPLE SWITCHER Step-Down Voltage Regulators provide all the active functions for a step-down (buck) switching regulator capable of driving a 0.5A load with excellent line and load regulation. The LM2575 and LM2575HV step-down voltage regulators provide all the active functions for a step-down (buck) switching regulator capable of driving a 1A load with excellent line and load regulation.
