RECOM Switching Regulator, 10-Pin SMD Package, 90% Efficiency - R-78AA-1.0 Series - R-78AA3.3-1.0SMD

Need to bump your power supply down a notch? This RECOM switching regulator does the trick. It dials loads down to an adjustable output between 3 and 5.5V DC, so your components get precisely the power they need. As shown by its ±0.4% line regulation rating, the converter's output stays stable to keep attached equipment running reliably. Kickstarting the device is a breeze thanks to its remote on/off control pin. Don't worry about wasting power, as this regulator converts up to 90% of voltages to provide energy-efficient switching.

Features & Benefits

• Short-circuit protection automatically restarts after tripping, cutting unnecessary downtime
• Solders to surfaces for quick and secure mounting
• Ripple voltage of just 30mV, minimising disruption from electrical interference
• Insulated plastic and epoxy housing boosts electrical safety
• Takes input voltages between 4.75 and 18V for versatile installation

Applications

• Automotive industry
• Control devices
• Industrial robotics

Can I use this switching regulator in time-sensitive applications?

Yes, the product's remote on/off function responds in just 50ms, allowing it to keep up with appliances that demand precise switching timing.
