The headline spec is 80 dB power-supply rejection ratio at 120 Hz — that's the ripple-kill figure for full-wave-rectified mains. For a 1 A load on a 12 V bus, this part cleans up the rectifier hash before it reaches sensitive analog or mixed-signal circuitry. ## 1.5 A output, 2 V dropout — sizing the headroom Rated 1.5 A continuous output with a 2 V maximum dropout at 1 A. That means the input must stay at least 7 V to hold regulation at full load. The 8 mA quiescent current is typical for a bipolar linear regulator — nothing exotic, but the thermal budget in the SOT-223 package needs the board copper to pull heat away. Over-temperature and short-circuit protection are built in, so a momentary overload won't kill the part. ## SOT-223 on tape-and-reel — assembly line fit Packaged in a TO-261-4 (SOT-223) surface-mount body, supplied on tape-and-reel or cut tape. The SOT-223 footprint is standard — three signal pins plus the large tab that doubles as the ground connection and the primary heat path. The 'NOPB' suffix confirms lead-free / RoHS-compliant construction.","metaTitle":"LM7805MPX/NOPB - TI 5V Fixed 1.5A Linear Regulator, SOT-223","metaDescription":"Texas Instruments LM7805MPX/NOPB is a 5V fixed-output linear regulator rated 1.5A in SOT-223 surface-mount package.
