The TSR 1E is a 1 Ampere step-down switching regulator series and a drop-in

replacement for inefficient 78xx linear regulators. This series comes in a stan-

dard plastic SIP-3 case and complements our existing POL portfolio with a se-

ries focusing strongly on a cost efficient design while maintaining our quality

standards. The effective design allows full load operation up to +60°C ambient

temperature without the need of any heat sink or forced cooling. The TSR 1E

switching regulators provide other significant features over linear regulators, i.-

e. better output accuracy, lower standby current and no requirement of external

capacitors. The TSR 1E series offers a broad application range in many envi-

ronments and is especially suited for high volume projects where the series will

help to reduce production cost by delivering not only a highly cost efficient but

also reliable solution.
