The
WRN78Uxx-500(B)
series
high
efficiency
switching
regulators
are
ideally
suited
to
replace
WRN78xx 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.
