VinMax. Vin(%)(%)8287909476818489DescriptionThe R-78xx-1.0 series high efficiency switching regulators are ideally suited to replace 1 Amp 78xx linearregulators and are pin compatible. The efficiency of up to 97% means that very little energy is wasted asheat so there is no need for any heat sinks with their additional space and mounting costs. Low ripple andnoise figures and a short circuit input current of typically only 10mA round off the specifications of thisversatile converter series.Specifications ( typical at 25°C, 10% minimum load, unless otherwise specified )CharacteristicsInput Voltage Range Output Voltage Range Output CurrentOutput Current LimitShort Circuit Input CurrentInternal Power DissipationShort Circuit ProtectionOutput Voltage Accuracy (At 100% Load)Line Regulation (100% Load, Vin max.)Load Regulation (10 to 100% full load)Dynamic Load StabilityRipple & Noise (20Mhz BW)Temperature CoefficientMax capacitance LoadSwitching FrequencyQuiescent Current Vin = min. to max. at 0% loadOperating Temperature RangeOperating Case Temperature (with derating)Storage Temperature RangeCase Thermal ImpendanceThermal ShutdownPackage WeightMTBF (+25°C).
