Traco Power Switching Regulator, Single Output, 75mV Pk-Pk Ripple and Noise - TSR 1 Series - TSR 1-2490

Is your electronic device taking a hit from surging inputs? Drop it a step down with this switching regulator from Traco Power. It takes in 12 to 36V DC and outputs a steady 9V DC to suit your system. An efficiency rating of 95% means you can be sure it wastes minimal energy while going about its business. This means you won't need to add a heat sink to your board, freeing up space for other components. Thanks to a mean time between failures of 5,350,000h, you can count on this unit to work around the clock in demanding conditions without taking a break.

Features & Benefits

• Wide operating temperature range between -40°C and +85°C to withstand harsh environments

• Pin-compatible with LMxx linear regulators for use with legacy devices

• Low output ripple and noise of 75mV Pk-Pk for reduced electrical disturbance

• Non-conductive plastic housing shields the system from electrical hazards

• Integrated short-circuit protection helps prevent damage from current surges

Applications

• Desktop computers

• Digital cameras

• Telecommunications networks

• Medical technology

How do I mount this regulator?

The device has built-in pins that are easily soldered to the through-holes on your board.
