L78MS05J

L78MS05JSMP

Overview

The 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.

Functions

• Strobe pin that controls the on/off state of the output voltage (active low input).

• 500mA output current.

Features

• TO-220-5H package for easier mounting and thermal design (L78MS05J).

• SMP5 package for easier mounting and thermal design (L78MS05JSMP).

• Low output off state current drain makes these devices optimal for saving power in applications.

• Full complement of built-in protection circuits (current limiter and thermal protection circuit).
