The LM series of monolithic integrated circuits provide all the active functions for a step-down buck switching regulator. Fixed versions are available with a 3. Adjustable versions have an output voltage range from 1. Both versions are capable of driving a 3A load with excellent line and load regulation. These regulators are simple to use because they require a minimum number of external components and include internal frequency compensation and a fixed-frequency oscillator.
