L7805CD2T-TR Positive Regulator: Features, Pin Configaruation, Diagrams

Product Overview

The L7805CD2T-TR is a three-terminal positive regulator, which is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. It can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, it can deliver over 1 A output current. Although designed primarily as a fixed voltage regulator, it can be used with external components to obtain adjustable voltage and currents.
