The R-78Bxx-Series high efficiency switching regulators are ideally suited to replace 78xx linear regulators
and are pin compatible. The efficiency of up to 97% 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 ver-
satile converter series.
Description
* add Suffix “L” for 90° bent pins, e.g. R-78B5.0-1.0L
Note 1: 1.5V, 1.8V Output can be unstable with Vin>26VDC
