(Ambient Temperature)

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.
