TRACOPOWER Switching Regulator, Through Hole, 1.2V dc Output Voltage, 4.6 → 36V dc Input Voltage, 1A Output

The Tracopower TSR-1 series of step-down switching regulators are great replacement for linear regulators as they solve many power supply problems. These DC to DC converters are up to 96% more efficient with built-in capacitors and short circuit protection. Allowing full load operation up to +60°C ambient temperature without the need of any heat sink or forced cooling. The TSR-1 switching regulators provide other significant features over linear regulators. Providing better output accuracy (±2%), lower standby current of 2 mA 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.
