Description
NCV78M12BDTRKG is a fixed-output 12‑V positive voltage regulator from On Semiconductor (NCV78M12 family). It’s a three‑terminal linear regulator that delivers a stable 12‑V rail from a higher input, with built‑in protection features such as current limiting and thermal shutdown for rugged operation. The BDTRKG suffix indicates a RoHS-compliant, lead‑free device in a specific package/reel format (package style and tape‑and‑reel details are indicated by the letters). Typical uses include simple, robust 12‑V power rails in automotive, industrial, and consumer electronics, where a compact, low‑noise regulator is advantageous. For exact electrical specs (allowed input range, dropout, maximum current, quiescent current, and thermal limits) consult the official datasheet.
Equivalent
Equivalent parts to NCV78M12BDTRKG (12V fixed regulator) include: LM7812 (and LM7812CV/CT), MC7812 (Onsemi), L78M12 (STMicroelectronics), KA78M12 (Renesas/KA family), NCP7812 (Onsemi), and NTE7812 (NTE Electronics). Any 12V fixed regulator in the 78xx/L78M series with similar current can substitute; verify pinout and package.
