The Pololu Corporation 3781 is a D36V28Fx series step-down (buck) voltage regulator. It provides a fixed output voltage of 3.3V with 4% accuracy and can deliver a typical maximum continuous output current of 3.6A. The input voltage range for this converter is from 4.5V to 50V.
This switching regulator is designed for high efficiency, rated at 90%, making it suitable for applications where power conservation is important. It features a 5-SIP Module package and is designed for Through Hole mounting.
Key features include reverse voltage protection up to 40V, output undervoltage and overvoltage protection, over-current protection, and short-circuit protection. A thermal shutdown feature helps prevent damage from overheating, and a soft-start feature limits inrush current during startup. The regulator has an input connector of NEMA 5-15P and an output connector that is a Barrel Plug with 1.3mm I.D. x 3.5mm O.D. It is designed for ITE (Commercial) applications and is approved by CCC, CE, cUL, cULus, and TUV.
The output voltage is 3.3V with 4% accuracy.
