Description
The GM78L00 series in positive voltage regulators are low-
cost devices providing a simple solution for a wide variety
of applications, which requires a regulated supply of up to
100mA.
These virtually indestructible positive voltage regulators
are protected by thermal shutdown and internal current-
limiting. Most applications require no external components.
The GM78L00 is very versatile. To use them as fixed volt-
age regulators in a wide range of applications, including
both local and on-card regulation for elimination of noise
and distribution problems associated with single-point regu-
lation. They can also be used with power pass elements to
make high current voltage regulators.
The GM78L00 offers impressive performance advantages
over old-fashioned zener diode-resistor combinations, pro-
viding lower output impedance and reduced quiescent cur-

A common ground is required between the input and the output voltages. The
input voltage must remain typically 2.0V above, the output voltage even during
the low point on the input ripple voltage.
