Switching
Regulator
Efficiency up to 94%, no need for heatsinks Pin compatible with LM78XX linears Low profile (L/W/H=11.5 x 7.55 x 10.2mm) Wide input range Short circuit protection, thermal shutdown Low ripple and noise IEC/EN60950-1 certified
DC/DC Converter
R-78-1.0
Description
The R-78xx-1.0 series switching
regulators are ideally suited to replace 1 Amp 78xx linear
regulators and are pin compatible. Efficiencies of up to 94% mean that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs.
