GU78XXA
Description
3-TERMINAL POSITIVE VOLTAGE REGULATORS
The GU78XXA series of fixed-voltage monolithic integrated-circuit voltage regulators designed for a wide range
of applications. These applications include on-card regulation for elimination of noise and distribution problems
associated with single-point regulation. Each of these regulators can deliver up to 1.5 amperes of output
current. The internal current limiting and thermal shutdown features of these regulators make them essentially
immune to overload.
