Datasheet

COO (Country of Origin):: TW

RECOM Switching Regulator, 220μF Maximum Capacitive Load, 1.65W Power Rating - R-78E-0.5 Series - R-78E3.3-0.5

Maintain a steady power supply to your equipment with this switching regulator from RECOM. It steps down an input voltage of 6 to 28V DC to an output voltage of 3.3V DC, making it a suitable choice for low-voltage applications. The regulator's body is MADE from Durable plastic that's resistant to impact and abrasion, so you can count on it for long-term performance. Thanks to an 88% efficiency level, there's minimal loss of energy through heat, for optimal productivity. Compact dimensions of 11.6 (L) x 8.5 (W) x 10.4mm (H) means the unit adds minimal bulk to your complex setups.
