The TSR-1 series step-down switching regulators are drop-in replacement 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 switching regulators provide other significant fea-
tures over linear regulators, i.e. 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.
