78M08

Product Overview

78M08 is commonly associated with 78M08 / L78M08 / MC78M08 series three-terminal positive fixed voltage regulators, available from multiple manufacturers such as STMicroelectronics, onsemi, New Japan Radio, UMW, Luguang and other compatible suppliers. The device is designed to provide a stable 8V regulated output for local on-card power regulation and general DC power supply circuits. With 500mA to 1A class output current depending on manufacturer and package, internal thermal overload protection, short-circuit protection and safe operating area protection, it is suitable for consumer electronics, industrial control boards, communication equipment, embedded systems, power supply modules and legacy regulator replacement projects.
