Replacement for R-78Axx-1.0SMD series
RoHS 6/6 Conform (100% Lead Free)
High Reflow Temperature SMD Package
Adjustable Output Voltage
Short circuit protection, Thermal shutdown
Remote On/Off Control
Very Low Shutdown Current
The R-78AAxx-1.0SMD series are manufactured without lead and meet the requirements for RoHS 6/6 as well as
the increased 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 94% means
that very little energy is wasted as heat. The additional features of remote on/off control and adjustable output volta-
ges will find many uses in the battery-powered, industrial, medical and automotive markets.
