TSR 1-2418

The TSR 1-2418 is a 1-output 1.8W through-hole-mount non-isolated step-down Switching Regulator for inefficient 78xx linear regulators. A high efficiency up to 96% allows full load operation up to +60°C ambient temperature without the need of any heat-sink or forced cooling. The TSR-1 drop-in replacement switching regulator provide other significant features over linear regulators, i.e. better output accuracy (±2%), lower standby current of 2mA 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.
