The MC78M00 Series positive voltage regulators are identical to the popular MC7800 Series devices, except that they are specified for only half the output current. Internal current limiting, thermal shutdown circuitry and safe−area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions.
The MC78M00 series are three‑terminal, 500 mA positive voltage regulators that provide regulated output without the need for external components. They incorporate internal current limiting, thermal shutdown, and safe‑area compensation for rugged operation.
The document includes maximum ratings, electrical characteristics for each voltage option (5 V, 8 V, 12 V, 15 V, etc.), package dimensions for TO‑220, DPAK‑3 and other packages, and ordering information. Protection features such as internal thermal overload protection and short‑circuit current limiting are also described.
