Three-Terminal
Medium Current Positive
Voltage Regulators
The MC78M00/MC78M00A 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.

MC78M00A High Accuracy (±2%) Available for 5.0 V, 8.0 V, 12 V
and 15 V
Previous Commerical Temperature Range has been extended to a
Junction Temperature Range of –40°C to +125°C

DEFINITIONS
Line Regulation – The change in output voltage for a
change in the input voltage. The measurement is made under
conditions of low dissipation or by using pulse techniques
such that the average chip temperature is not significantly
affected.
Load Regulation – The change in output voltage for a
change in load current at constant chip temperature.
Maximum Power Dissipation – The maximum total
device dissipation for which the regulator will operate within
specifications.
Input Bias Current – That part of the input current that is
not delivered to the load.
Output Noise Voltage – The rms AC voltage at the
output, with constant load and no input ripple, measured over
a specified frequency range.
Long Term Stability – Output voltage stability under
accelerated life test conditions with the maximum rated
voltage listed in the devices’ electrical characteristics and
maximum power dissipation.
