K78XXYMD-2000 product is a high efficiency switching
regulator, 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.
They are widely used in industrial control, instrumentation,
and electric power applications.
