Transistor and Voltage Regulator Icon Set - Electronic Component Illustrations #3874917 (License: Personal Use)

The image displays two schematic-style electronic component icons on a black background. On the left is a TO-220 packaged transistor with a gray body, circular marking, green thermal pad, and three vertical leads; on the right is a three-pin surface-mount or through-hole regulator/IC with a yellow top, red polarity dot, gray body, and three leads. Both use consistent flat-color styling for technical documentation or web interfaces.

Used in electronics learning platforms, PCB design software UIs, engineering blogs, or product datasheets to visually represent common active components without photorealism. Matches user intent for quick identification, instructional diagrams, or icon libraries.
