Features ● Efficiency up to 97%,Non isolated, INNOLINE no need for heatsinks ● Pin-out compatible with LM78XX Linears DC/DC-Converter ● Low profile( L*W*H=11.5*8.5*17.5mm) with 3 year Warranty ● Wide input range.(4.75V ~ 34V) ● Short circuit protection, Thermal shutdown ● Non standard outputs available as specials between 1.5V ~15V ● Low ripple and noise ● “L” version with 90° pins 1.0 AMP ● See Innoline Application Notes for use as an inverter (alternative to LM79xx Linear) SIP3 Description Single Output 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.
