THREE±TERMINAL MEDIUM |
||||||||
The MC78M00/MC78M00A Series positive voltage regulators are |
||||||||
identical to the popular MC7800 Series |
devices, except that they are |
CURRENT POSITIVE FIXED |
||||||
specified for only half the output current. Like the MC7800 devices, the |
||||||||
VOLTAGE REGULATORS |
||||||||
MC78M00 three±terminal regulators are intended for local, on±card voltage |
||||||||
regulation. |
|

|
|
|
SEMICONDUCTOR |
|
Internal current limiting, thermal shutdown circuitry and safe±area |
||||||||
compensation for the internal pass transistor combine to make these |
TECHNICAL DATA |

devices remarkably rugged under most operating conditions. Maximum |
|
