R-78AA-0.5
Description
The R-78AAxx-0.5SMD series are adjustable output non-isolated buck converters that meet
the requirements for RoHS 10/10 as well as the reflow soldering temperatures associated with
vapor phase soldering, making these high efficiency switching regulators ideally suited to modern
pick-and-place mass production. The efficiency of up to 97% means that very little energy
is wasted as heat. The additional features of remote on/off control, continuous short circuit protection
and adjustable output voltages will find many uses in the battery-powered, industrial, medical and
automotive markets.
