The L7905CV-DG is a linear, fixed voltage regulator manufactured by STMicroelectronics. It is offered as a three-terminal negative regulator in a TO220 package with thermal dissipation. This device produces a fixed output voltage of -5 V and can deliver up to 1.5 A of output current. It features internal current and thermal limiting, as well as internal short-circuit protection. It also includes an input voltage range from 10.5 V to 33 V. The device offers excellent regulation and very low noise performance when used for applications requiring an output voltage of -5 V. It is an ideal device for precision power supplies, where excellent regulation and low noise are desired.
