Features and Applications

The RT8251GSP is a monolithic step-down switch mode converter with a built-in internal power MOSFET and 5 A continuous output current. Available in a SOP-8 package.

The RT8251 provides protection functions such as cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the regulator draws 25 μA of supply current.
