Efficiency up to 97%,Non isolated, no need for heatsinks Pin-out compatible with LM78XX Linears Low profile( L*W*H=11.5*8.5*17.5mm) Wide input range.(4.75V ~ 34V) Short circuit protection, Thermal shutdown Non standard outputs available as specials Features INNOLINE DC/DC-Converter with 3 year Warranty between 1.5V ~15V Low ripple and noise "L" version with 90 pins See Innoline Application Notes for use as an inverter (alternative to LM79xx Linear) 1.0 AMP SIP3 Single Output Description The R-78Bxx-1.0 Series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. The L-Version with 90 pins allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series.
