ON Semiconductor MC78M00 MC78M00A Series Manual
The MC78M00/MC78M00A series are three‑terminal positive voltage regulators intended for local, on‑card regulation. They provide up to 500 mA of output current and include internal current limiting, thermal shutdown, and safe‑area compensation for rugged operation.
The datasheet lists electrical characteristics for a range of output voltages (5 V to 24 V), maximum ratings such as input voltage 5‑18 V, dropout voltage around 2 V, and package options including TO‑220 and DPAK‑3. Package dimensions and thermal resistance data are also provided for proper heat‑sink design.
