STANDARD APPLICATION
A common ground is required between the input
and the output voltages. The input voltage must
remain typically 1.1 V more negative even during
the high point of the input ripple voltage.
These two digits of the type number indicate
nominal voltage.

500 mA Negative Voltage
Regulators
The MC79M00 series of fixed output negative voltage regulators
are intended as complements to the popular MC78M00 series devices.
Available in fixed output voltage options of –5.0, –8.0, –12 and –15
V, these regulators employ current limiting, thermal shutdown, and
safe–area compensation – making them remarkably rugged under
most operating conditions. With adequate heatsinking they can deliver
output currents in excess of 0.5 A.
