LM2576HVT-ADJ 3A Adjustable Step Down Voltage Regulator

The LM2576HVT-ADJ 3A Adjustable Step Down Voltage Regulator is a compact, switch-mode step-down (buck) regulator designed to provide an adjustable, regulated DC output from a higher-voltage input. With a rated output current of up to 3 amps, this module is appropriate for use where efficient voltage conversion and reduced heat dissipation are important compared with linear regulators.

This adjustable version allows the output voltage to be set by external resistors, giving designers flexibility to tailor the supply to a wide range of circuits and subsystems. Its step-down topology means it converts higher input voltages to lower, stable outputs while minimizing wasted power, making it well suited for battery-powered systems, embedded electronics, prototyping, bench power supplies, and industrial control circuits.

The regulator is commonly used as a building block in power supply designs where a reliable, compact DC regulator is required. It integrates the switching regulator function into a single package and requires only a few external components to implement a complete regulated power source, which simplifies circuit layout and assembly.

When selecting this part, confirm compatibility with your input voltage range, output setting method, and thermal or mounting requirements in your application to ensure reliable operation.
