Additional Infomation About Product

Efficiency up to 97%, no heatsinks required Pin compatible with LM78XX linears Features Low profile (L/W/H=11.5 x 8.5 x 17.5mm) DC/DC Converter Wide input range Short circuit protection, thermal shutdown Switching Low ripple and noise L version with 90 pins Regulator R-78B-1.0(L) Positive to negative converter Description 1.0 Amp The R-78Bxx-1.0 series high efficiency switching regulators are ideally suited to replace 78xx SIP3 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 Single Output 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.
