RECOM Switching Regulator, 79 to 89% Efficiency, 100mV Maximum Ripple Voltage - R-78C-1.0 Series - R-78C3.3-1.0

Control the output voltage of your battery-powered devices with this switching regulator from RECOM. As it has a wide input voltage range between 7 and 42V DC, it's a versatile option that handles many common power supplies, converting them to a 3.3V DC output. With its built-in short circuit protection, the unit automatically recovers after electrical faults to minimise appliance downtime. A line regulation rating of ±0.2% means it provides a steady output voltage, so you can be sure of a reliable power supply.

Features & Benefits

• Through-hole mounting style for easy installation onto circuit boards

• Compact dimensions of 11.6 (L) x 8.5 (W) x 10.4mm (D) to take up minimal space on a crowded PCB

• Power rating of 3.3W for energy-efficient voltage switching

• Wide operating temperature range between -40°C and +68°C for use in harsh industrial environments

Applications

• Portable cameras

• Instrumentation

• Commercial garages

• Film industry

Do I need to use a heatsink with this switching regulator?

No, you don't need to install a heatsink with this component. Its maximum efficiency rating of 89% means it experiences minimal heat build-up from energy loss.
