The LM2574 is a set of fixed and adjustable switching voltage regulators that are simple to use. The LM2574 has all of the active circuitry needed to build a step-down (buck) switching regulator with only a few external components.
The LM2574 is available in 3.3V and 5V fixed output versions, or an adjustable version with an output voltage range of 1.23V to 37V. The output voltage is guaranteed to be ±4% for specified input and load conditions.
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.
