L78M05ABV Description

Short technical summary and product information.

The STMicroelectronics L78M05ABV is a precision 5V linear voltage regulator from the L78MxxA series. It is designed to provide a stable 5V output with an output current capability of up to 0.5A (500mA). This device is useful in a wide range of applications requiring on-card regulation, helping to eliminate distribution problems associated with single-point regulation.

 

Key features include internal current limiting, thermal shutdown, and safe area protection, making the device highly reliable. The output voltage tolerance is ±2%. The regulator operates within an extended temperature range of -40°C to 125°C.

 

Packaged in a TO-220 package, the L78M05ABV is designed for through-hole mounting. Its robust design ensures it is essentially indestructible if adequate heat sinking is provided. While primarily a fixed voltage regulator, it can be used with external components to achieve adjustable voltage and current outputs.
