Features INNOLINE Efficiency up to 97%,Non isolated, no need for heatsinks Pin-out compatible with LM78XX Linears Very low profile( L*W*H=11.5*7.5*10.2 ) Wide input range.(4.75V ~ 32V) Short circuit protection, Thermal shutdown Non standard outputs available as specials Low ripple and noise UL94V-0 package material EMC, Safety Certified See Innoline Application Notes for use as an inverter (alternative to LM79xx Linear) DC/DC-Converter 0.5 AMP SIP3 Single Output Description The R-78xx-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. Low ripple and noise figures and short circuit , overload and overtemperature protection round off the specifications of this versatile converter series.This R-78xx-0.5 is fully certified to EN 60601-1-2 (Medical Equipment), EN 55022 (Emissions), and EN55024 (Immunity) EMC Standards and for EN-60950-1 Safety.
