APPLICATIONS
Upgraded K78xx-2000(L) series switching
regulators are ideal replacement for K78xx
linear regulators and LDOs. The efficiency of
up to 92% 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. They are widely used in
industrial control, instrumentation, and electric
power applications.
