Overview
The L7815ACD2T-TR is a three-terminal positive voltage regulator from STMicroelectronics, part of the L78 series. This regulator is available in the D²PAK package and offers a fixed output voltage of 15V. It is designed to provide local on-card regulation, eliminating the distribution problems associated with single point regulation. The L7815ACD2T-TR embeds internal current limiting, thermal shut-down, and safe area protection, making it highly reliable and essentially indestructible if adequate heat sinking is provided. It can deliver up to 1.5 A of output current and is suitable for a wide range of applications due to its robust features and extended temperature range operation.
