TRACOPOWER Switching Regulator, Through Hole, 6.5V dc Output Voltage, 8 → 35V dc Input Voltage, 500mA Output

The Tracopower TSR 0.5 series of step-down switching regulators are drop-in replacement for inefficient LM78 linear regulators. These DC-DC converters have a high efficiency up to 97%, which allows full load operation up to +80°C (+90°C with 50% load) ambient temperature without the need of any heat-sink or forced cooling. The TSR 0.5 switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±3 %), lower standby current and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.
