The V7805W-500R is a high-efficiency, non-isolated switching regulator designed for versatile power conversion applications. Manufactured by BEL/CUI INC and available from ThinkRobotics, this compact module provides a reliable 5 Vdc output from a wide input voltage range of 9~72 Vdc, supporting loads up to 500 mA.
Constructed with a robust plastic case (UL94-V0), the converter measures 11.5 x 9.0 x 17.5 mm and weighs only 4 grams, making it suitable for space-constrained environments. Its pin configuration is comparable to LM78 linear regulators, facilitating easy integration into existing designs.
