APPLICATIONS
The K78LXX-1000 series high efficiency
switching regulators are ideally suited to
replace 78xx linear regulators and are pin
compatible. The efficiency of up to 96% 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.
