RECOM Switching Regulator, 4.75 to 32V DC Input Voltage Range, 3.3V DC Output Voltage - R78HB Series - R-783.3-0.5

Maintain a stable output voltage in your electrical devices using this switching regulator from RECOM. It's pin-compatible with linear regulators from the LM78xx range so you can replace them with this component to upgrade your system. The through-holes in its body let you quickly fit this unit into a machine without the need to drill mounting holes in it. A wide operating temperature range between -40°C and +85°C means it can withstand demanding conditions.

Features & Benefits

• Built-in short circuit protection helps prevent damage from current malfunction

• Broad input voltage range between 4.75 and 32V DC for versatility

• MTBF of 21,098,000 hours for lasting performance

• Efficiency rating of 91% for reduced energy consumption

Applications

• Manufacturing industry

• Medical technology

• Agricultural equipment

• Computer devices

What's the difference between a switching regulator and a linear regulator?

While a switching regulator stores excess voltage in its transistor leading to lower energy waste, a linear regulator releases excess voltage as heat. As switching regulators use less power and are more efficient, you'll typically find them used in devices with high input voltage ratings.
