TSR 1E Switching Regulators
TSR 1E Switching Regulators

Traco Power has introduced the TSR 1E a 1A step-down switching regulator series as a drop-in replacement for the 78Xx linear regulators. The series is designed in a standard plastic SIP-3 case to compliment the existing POL portfolio by providing a cost-efficient design along with the quality standards. The unique design allows full load operation up to +60°C ambient temperature without the need for any heat sink or forced cooling.


The TSR 1E is designed with many significant features over linear regulators such as better output accuracy, lower standby current, no requirement of external capacitors. The TSR 1E series can be used in a wide range of applications in many environments, especially for high volume projects to reduce production cost by delivering highly cost-efficient and reliable solutions.


Features of TSR 1E Switching Regulators

  • Highly cost-efficient design
  •  Pin compatible with LMxx linear regulators
  •  Operation Temperature Range: –40°C to +85°C
  •  Efficiency up to 92%
  •  Wide input operating range: 6-36 VDC
