Features, Applications

Efficiency 96%, No Heatsinks Required 2A Continuous Output Current Vin To 32V Vout: - 15V Wide Operating Temperature +70C at Full Load Continuous Short Circuit Protection Pin Compatible With TO220 Linear Regulators Positive To Negative

The R-78Bxx-2.0 series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency to 96% means that very little energy is wasted as heat. Full power is available over a temperature range to 70C without the need for heatsinks with their additional space and mounting costs. A high input voltage to 32VDC and output voltages from to 15V, low ripple and noise figures and a short circuit input current of typically only 50mA round off the specifications of this versatile converter series.
