Description
The L7812CD2T is a classic, widely-used positive voltage regulator integrated circuit (IC) designed to provide a fixed, stable +12V DC output from a higher, unregulated input voltage. As part of the 78xx series, it is renowned for its simplicity, robustness, and ease of use. It requires only a couple of external capacitors for basic operation and includes built-in protection features such as thermal overload shutdown, short-circuit protection, and output current limiting (up to 1A). Housed in a standard TO-263 (D2PAK) surface-mount package with excellent thermal characteristics, it offers a reliable and cost-effective solution for providing a local, regulated power rail.
