L78M15ABV Description

Short technical summary and product information.

The L78M15ABV from STMicroelectronics is a precision positive voltage regulator designed for a wide range of applications. It offers a fixed output voltage of 15V and can deliver an output current of up to 0.5A when adequate heat sinking is provided.

 

Key features include internal current limiting, thermal shutdown, and output transition SOA protection, making the device highly reliable and essentially indestructible under normal operating conditions. The regulator has an output voltage tolerance of ±2% and operates reliably within an extended temperature range of -40°C to 125°C.

 

This device is available in a TO-220 package, suitable for through-hole mounting. Its design allows for local on-card regulation, simplifying power distribution and eliminating associated problems. While primarily designed as a fixed voltage regulator, it can be used with external components to achieve adjustable voltage and current outputs.

 

The L78M15ABV is useful in various applications requiring stable voltage regulation, such as power supplies, battery chargers, and general electronic circuits. Its robust protection mechanisms ensure safe operation even in demanding environments.
