Overview
The L7815ACV-DG is a three-terminal positive voltage regulator from STMicroelectronics, part of the L78 series. This regulator is available in the TO-220 package and is designed to provide a fixed output voltage of 15V. It is highly versatile and can be used in a wide range of applications due to its robust features and multiple package options.
The L7815ACV-DG can provide local on-card regulation, which helps in eliminating the distribution problems associated with single point regulation. It embeds internal current limiting, thermal shut-down, and safe area protection, making it essentially indestructible if adequate heat sinking is provided. This regulator can deliver up to 1.5 A of output current and is guaranteed to operate in an extended temperature range.
