The L78MS05, L78MS05J and L78MS05JSMP are general-purpose constant voltage power supplies that feature an output current of 500mA and a built-in on/off function.

The current drain in the output off state is low, making these devices effective for reducing power consumption in application equipment. The surface mounting package can contribute to miniaturization and improved efficiency. These devices are optimal for use in all types of AV and OA equipment and in automotive applications (such as power supplies for meters) as well.
