Standard linear regulators LM78XX and LM79XX have been the industry workhorse for almost 50 years now. They are simple to use devices which are available in various industry standard packages. These linear devices are in-efficient and will need good thermal management when the current drawn exceeds 500mA. Recom, Murata, Tracopower, XP Power, Aimtec, CUI and others support a cost-effective replacement for these standard 78XX and 79XX devices. The replacement devices are non-isolated switched mode DC-DC converters and are designed to work with conversion efficiencies of >90%.

Wide input range integrated switching regulators including Plus-to-Minus ISRs: More efficient, more accurate and lower standby current than the linear regulators they replace, with no external capacitors. Variety of industry-standard voltages. High efficiencies and small footprints without heatsinks. Wide operating temperature ranges, thermal shutdown and short-circuit protection. LM78XX pin/size-compatible alternatives.
