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. 1.0 Amp SIP3 3 Single Output Selection Guide Part Number R-781.8-1.0 R-782.5-1.0 R-783.3-1.0 R-785.0-1.0 Input Voltage Range [VDC] 4.75 - 18 4.75 - 18 4.75 - 18 6.5 - 18 Output Voltage [VDC] 1.8 2.5 3.3 5.0 Output Efficiency Current @ min Vin @ max.
