Detailed Information see
Application Notes chapter "MTBF"
The R-78xx-1.0 series switching regulators are
ideally suited to replace 1 Amp 78xx linear regulators
and are pin compatible. Efficiencies 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.
