APPLICATIONS
The K78UXX-500(L) series high efficiency
switching regulators are ideally suited to replace
LM78xx linear regulators and are pin compatible. It
has ultra wide input voltage range ,the efficiency of
up to 95% means that very little energy is wasted
as heat so there is no need for any heatsinks with
their additional space and mounting costs.
