Description

The R-78Axx-1.0SMD series high efficiency switching regulators are ideally suited to pick-and-place mass

production. The efficiency of up to 94% means that very little energy is wasted as heat. remote on/off control

and adjustable output voltage are useful additional features of this versatile SMD converter series.
