ONSEMI MC7805CDTG 7805 Linear Voltage Regulator, 5V 1A, Surface Mount, TO-252-3

The ONSEMI MC7805CDTG is a fixed linear voltage regulator designed for a wide range of applications, including local and on-card regulation. This device is built to deliver reliable performance with internal current limiting, thermal shutdown, and safe-area compensation to protect against overload and fault conditions. With adequate heat sinking, the regulator can supply output currents in excess of 1A, making it suitable for various power management tasks.

The MC7805CDTG offers a fixed 5V output with a nominal input voltage range of 10V to 35V. It is a stable and efficient solution for applications requiring a consistent voltage supply. While primarily a fixed regulator, it can be used with external components to obtain adjustable voltages and currents, providing flexibility in circuit design.

Key Benefits

• No external components required for standard fixed-voltage operation
• Internal thermal overload protection ensures safe operation under high-temperature conditions
• Internal short-circuit current limiting provides robust fault protection
• Output transistor safe-area compensation enhances device reliability
• Output voltage tolerance options of 1.5%, 2%, and 4% are available

This surface-mount IC is housed in a TO-252-3 package with 3 pins, operating over a temperature range of 0°C to 125°C. The compact design and high performance make it an excellent choice for motor drive control and other embedded power applications.
