THREE–TERMINAL MEDIUM  
CURRENT POSITIVE FIXED  
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.  
SEMICONDUCTOR  
TECHNICAL DATA  
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.
