MC7800 is a 1.0A positive voltage regulator produced by Semiconductor Components Industries. It can be used in a variety of applications, including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation.
The MC7800 series comprises positive‑voltage linear regulators (MC7800, MC7800A, MC7800AE, NCV7800) designed for a wide range of applications, offering fixed output voltages with options for external component adjustment. They feature internal current limiting, thermal overload protection, and safe‑area compensation, and can deliver output currents in excess of 1 A when properly heatsunk.
Key data include typical output voltages from 5 V to 8 V, an input voltage range of 5 V to 35 V, thermal resistance of 15 °C/W (junction‑to‑ambient), and availability in DPAK‑3, D2PAK‑3, and TO‑220‑3 packages. The datasheet also contains ordering information, package dimensions, and regulatory notes.
