About the product
The R-78K-1.0 series is a switching regulator module that has been designed to offer all the advantages of a switching regulator (high efficiency, wide input range, accurate output voltage regulation) but with a low cost for production quantities. Due to the R-78K-1.0’s high efficiency of up to 95% no heat-sink is required, and operation from -40 to 90°C is possible with slight derating. The compact TO-220 compatible SIP3 package measures only 11.5 x 7.55 x 10.2mm, so it saves precious board space.
