Description

The G5ULM2576 series of regulators are monolithic integrated circuits that provide all active functions f or a step-down (buck) switching regulator , capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltage of 3.3v , 5v , 12v , 15v and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator .
