Dual low-noise operational amplifiers(Dual power supply type)
The M5220 is a voltage regulator IC manufactured by Mitsubishi. It is a three-terminal positive voltage regulator with a fixed output voltage of 5V. It has a maximum output current of 1A and a maximum dropout voltage of 1.5V. The M5220 is available in a DIP-8 package. The M5220 is designed to provide a regulated output voltage with a minimum of external components. It has a built-in thermal shutdown circuit that protects the device from overheating. It also has a built-in current limiting circuit that limits the output current to a safe level. The M5220 is suitable for use in a wide range of applications, including automotive, industrial, and consumer electronics. It can be used to provide a regulated 5V supply for microprocessors, memory, and other digital circuits. It can also be used to provide a regulated 5V supply for analog circuits such as operational amplifiers and comparators. (For reference only)
