The R-78Bxx-1.5 Series high efficiency switching regulators are ideally suited to replace 78xx linear regula-
tors and are pin compatible. The efficiency of up to 95% means that very little energy is wasted as heat so
there is no need for any heat sinks with their additional space and mounting costs. The L-Version with 90°
pins allows direct replacement for laid-flat regulators where component height is at a premium.Low ripple
and noise figures and a short circuit input current of typically only 10mA round off the specifications of this
versatile converter series.
