LM2596S-Adj – 150KHz 3A Step-Down Voltage Regulator – TO-263 Package

LM2596S-Adj – 150KHz 3A Step-Down Voltage Regulator – TO-263 Package

The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, 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.
The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller-sized filter components than what would be required with lower frequency switching regulators.
