Product Details
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.
