1.5 Amp POL Switching Regulators In Cost Efficient Open Frame Design

Offers a broad application range in many environments and is especially suited for high volume projects by reducing production cost

The TSR 1.5E by Traco Power is a 1.5 Ampere step-down switching regulator series and a drop-in replacement for inefficient LM78xx linear regulators. This series comes in a compact SIP-3 open frame package and complements the company’s existing POL portfolio with a series focusing strongly on a cost-efficient design while maintaining quality standards. 

There are 3 output voltages available: 3.3, 5.0 and 12VDC. The effective design allows full load operation from –40 degrees Celsius up to +85 degrees Celsius ambient temperature without the need for any heat sink or forced cooling. 

Other features

  • Pin compatible with TO-220 package linear regulators
  • Efficiency up to 97% 
  • Wide input operating range 7-36 VDC 
  • Short circuit protection 
  • Excellent line/load regulation

The TSR 1.5E switching regulators also provide significant features such as better output accuracy, lower standby current and no requirement of external capacitors. The TSR 1.5E series offers a broad application range in many environments 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.
