The LM2574 family is a series of easy-to-use fixed and adjustable switching voltage regulators. The LM2574 contains all of the active circuitry necessary to construct a step-down (buck) switching regulator and requires a minimum of external components. The LM2574 can supply 0.5A while maintaining excellent line and load regulation. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
