Recom R-78B Switching Regulator

The R-78Bxx-2.0 series high efficiency switching regulators are ideally suited to replace 78xx linear
regulators and are pin compatible. The efficiency of up to 96% means that very little energy is wasted
as heat. Full power is available over a temperature range of -40°C up to 70°C without the need for
heatsinks with their additional space and mounting costs. A high input voltage of up to 32 V dc and
output voltages from 1.2 V up to 15 V, low ripple and noise figures and a short circuit input current of
typically only 50mA round off the specifications of this versatile converter series.

Features and Benefits

• Efficiency Up To 96%, No Heatsinks Required
• 2 A Continuous Output Current
• Vin Up To 32 V
• Vout: 1.2 V - 15 V
• Wide Operating Temperature -40°C to +70°C at Full Load
• Continuous Short Circuit Protection
• Pin Compatible With TO220 Linear Regulators
• Positive To Negative
