4.95W DC/DC converter, input 4.75...18V, output 3.3V/1500mA, SIP3

The highly efficient switching regulators of the R-78Bxx-1.5 series are ideal as a replacement for the 78xx linear regulators and are pin-compatible. The efficiency of up to 95% means that very little energy is wasted in the form of heat, so that no heat sinks with their additional space and assembly costs are required. The L version with 90° pins allows direct replacement of lay-flat regulators where component height is an issue. Low ripple and noise values and a short-circuit input current of typically only 10mA round off the specifications of this versatile converter series.
