The GM7800 series are classic regulators useful in a
wide range of applications. For example, you can use
them for local on-card regulation to eliminate the
distribution problems associated with single point
regulation.
The wide range of output voltages voltages (5V to 27V)
make them useful in an endless list of applications.
Although designed as fixed voltage regulators, you can
add a few external components to make adjustable
voltages and currents.
Current limiting prevents the peak output current to a
safe value. Safe-area protection for the output transistor
limits internal power dissipation. If internal power
dissipation becomes too high for the heat sinking
provided, the thermal shutdown circuit activates to
prevent the regulator from overheating. These versatile
workhorses are easy to use. You do not need to bypass
the output, although this does improve transient
response. Input bypassing is needed only if you place
the regulator far from the filter capacitor of the power
supply.
The GM7800 series is available in TO-220, TO-252 and
TO-263 packages.
