Overview
The STMicroelectronics L7815CV-DG is a fixed positive linear voltage regulator IC, part of the L78 Series. This three-terminal positive voltage regulator provides a stable 15V output from input voltages ranging from 17.5V to 35V. It is designed to deliver up to 1.5A of output current and is housed in a TO-220-3 package. The L7815CV-DG is particularly useful in applications requiring local on-card regulation, eliminating the problems associated with single point regulation. It features internal current limiting, thermal shutdown, and safe area protection, making it highly reliable and durable.
