Features ● ● ● ● ● ● ● ● INNOLINE Efficiency up to 96%, no need for heatsinks! Pin-out compatible with LM78XX Linear Regs. Low profile (L*W*H=11.6*8.5*10.4mm) Wide input range (5V ~ 42V) Short circuit protection, thermal shutdown Non-standard outputs available as specials Low ripple and noise See Innoline App Notes for use as a positive-tonegative inverter (alternative to 79xx regulator) DC/DC-Converter with 3 year Warranty 1.0 AMP SIP3 Single Output Description The R-78Cxx-1.0 series switching regulators are ideally suited to replace 1 Amp 78xx linear regulators and are pin compatible. Efficiencies of up to 96% means that very little energy is wasted as heat and the high input voltage is a useful feature.
