GM78L00
100 mA POSITIVE VOLTAGE REGULATORS
Wide range of Fixed Output Voltages
Output Current up to 100 mA
No External Components Required
Internal Thermal Overload Protection
Internal Short Circuit Current-Limiting
Available in TO-92, SOT-89 and SOP-8 packages
The GM78L00 series of positive voltage regulators are low-cost
devices providing a simple solution for a wide variety of applica-
tions requiring a regulated supply of up to 100mA.
These virtually indestructible positive voltage regulators are pro-
tected by thermal shutdown and internal current-limiting. Most
applications require no external components.
The GM78L00’s are very versatile. Use them as fixed voltage regu-
lators in a wide range of applications, including local on-card regu-
lation for elimination of noise and distribution problems associated
with single-point regulation. They can also be used with power
pass elements to make high current voltage regulators.
The GM78L00’s offer impressive performance advantages over old-
fashioned zener diode-resistor combinations, providing lower out-
put impedance and reduced quiescent current, along with lower
noise.
