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-
