Description
LM2575 of regulators provides all the active functions for a step- down (buck) switching regulator, and drives 1A load with excellent line and load regulation.
LM2575 is available in fixed output volt ages of 3.3V, 5V, 12V, 15V and a versatile Adjustable output
version. These regulators are simple to use and require a minimum number of external components.
