RECOM Switching Regulator, Surface Mounting, Adjustable Output - R-78AA-0.5 Series - R-78AA3.3-0.5SMD
A calm port in a Storm – that's what you GET with this switching regulator from RECOM. It stabilises varying voltage inputs ranging from 4.75 to 32V DC to give you a steady 3.3V DC output that's safe for low-voltage components like LED lamps. As an added advantage, you can adjust the output between 3 and 5.5V to suit your system's needs. The unit comes with integrated ON/OFF controls, so you can keep a secure handle on its operation.
Features & Benefits
• Non-conductive plastic housing for impact resistance and prevention of electric shocks
• Continuous short-circuit protection with automatic recovery to ensure safe operation
• Broad operating temperature range between -40°C and +85°C for use in challenging settings
• Low ripple and noise rating of 30mV for smooth signal transmission
Applications
• Medical equipment
• Research laboratories
• Automotive manufacture
How do I mount this switching regulator?
For ease, you can surface-mount this regulator directly onto your equipment via vapour phase soldering.
How efficient is this switching regulator?
This device offers up to 91% efficiency, which means it loses next to nothing in heat, saving you the bother of installing a heatsink.
