Three-Terminal
Medium Current Positive
Voltage Regulators
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. Like the MC7800 devices, the MC78M00 three–terminal
regulators are intended for local, on–card voltage regulation.
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. Maximum output
current, with adequate heatsinking is 500 mA.
