Traco Power TSN 1-2490, 7,5 mm, 16,5 mm, 11,7 mm, 3,1 g, 11.5 - 32 V, 1000 mA

The new TSN-1 series step-down switching regulators are drop-in replacement for inefficient LM79xx linear regulators. A high efficiency up to 96 % allows full load operation up to +70°C (+85°C with derating) ambient temperature without the need of any heat-sink or forced air cooling. The TSN-1 switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2 %), lower standby current of ~2 mA and no requirement of external capacitors. They are suitable for negative output circuits. The high efficiency and low standby power consumption make these regulators an ideal solution for energy sensitive applications.
