ONSEMI LM2576 Adjustable DC-DC Step-Down Regulator, 7-40V in, 3A out

The ONSEMI LM2576D2T-ADJG is a high-performance, monolithic step-down switching regulator designed to deliver a robust 3A output, making it ideal for efficient power management solutions. This regulator simplifies power supply design by minimising the number of required external components, streamlining your project development.

As a switch-mode power supply, it offers significantly higher efficiency compared to standard three-terminal linear regulators, particularly when dealing with higher input voltages. This makes it an excellent choice for reducing power loss and heat generation in your applications. Key features include cycle-by-cycle current limiting and integrated thermal shutdown, providing comprehensive protection under fault conditions to ensure reliable operation.

The regulator also boasts TTL shutdown capability and a low-power standby mode, enhancing its versatility for power-sensitive designs. It operates with readily available standard inductors, further easing the component selection process. With an adjustable output voltage range from 1.23V to 37V and a wide input range of 7V to 40V, it offers exceptional flexibility for various circuit requirements.

Encased in a surface-mount TO-263-5 package, this component is built for durability and performance in demanding environments, with an operational temperature range from -40°C to 125°C.
