Specifications
( typical at 25°C, 10% minimum load, unless otherwise specified )
The R-78Cxx-1.0 series switching regulators are ideally suited to replace 1 Amp 78xx linear regulators and are pin
compatible. Efficiencies of up to 96% means that very little energy is wasted as heat and the high input voltage is a
useful feature.
