产品概览
The LM7805MP from Texas Instruments is a fixed 5V, 1.5A positive linear voltage regulator in an SOT-223 surface-mount package. With 7V to 35V input range and 2V typical dropout at 1A, it provides a robust and simple 5V supply with internal thermal shutdown, overcurrent protection, and output short-circuit protection.
