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.
