Description
The R-78AAxx-0.5SMD 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 97% means
that very little energy is wasted as heat. The additional features of remote on/off control and adjustable output
voltages will find many uses in the battery-powered, industrial, medical and automotive markets.

Optional Protection Circuit
Optional Protection 2:
Optional Protection 1:
Add a blocking diode to Vout
if current can flow backwards
into the output, as this can
damage the converter when it
is powered down.
The diode can either be fitted
across the device if the
source is low impedance or
fitted in series with the output
(recommended).
