Overview
Features 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.
