PRELIMINARY
GM78L00
100 mA POSITIVE VOLTAGE REGULATORS
www.DataSheet4U.com
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.
