Features Switching Regulator • Efficiency up to 97%, no need for heatsinks • Pin-out compatible with LM78XX linears • Very low profile • 4.75V - 32V Wide input range • Short circuit protection, thermal shutdown • Low ripple and noise • IEC/EN60950-1 certified • Positive to negative converter DC/DC Converter R-78-0.5 Description The R-78xx-Series high efficiency switching regulators are ideally suited to replace 78xx linear regultors 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 over-temperature protection round off the specifications of this versatile converter series. This R-78xx-0.5 is fully certified to EN55032 EMC Standard and for IEC/EN-60950-1 + AM2 Safety. 0.5 Amp SIP3 3 Single Output Selection Guide Part Number R-781.5-0.5 R-781.8-0.5 R-782.5-0.5 R-783.3-0.5 R-785.0-0.5 R-786.5-0.5 R-789.0-0.5 R-7812-0.5 R-7815-0.5 Input Voltage Range [VDC] 4.75 - 30 (1) 4.75 - 32 4.75 - 32 4.75 (2) - 32 6.5 - 32 8.0 - 32 11 - 32 15 - 32 18 - 32 Output Voltage [VDC] 1.5 1.8 2.5 3.3 5.0 6.5 9.0 12 15 Output Efficiency Current @ min Vin @ max.
