3 Description
The LM340 and LM7805 Family monolithic 3-terminal
positive voltage regulators employ internal current-
limiting, thermal shutdown and safe-area
compensation, making them essentially indestructible.
If adequate heat sinking is provided, they can deliver
over 1.5-A output current. They are intended as fixed
voltage regulators in a wide range of applications
including local (on-card) regulation for elimination of
noise and distribution problems associated with
single-point regulation. In addition to use as fixed
voltage regulators, these devices can be used with
external components to obtain adjustable output
voltages and currents.
Considerable effort was expended to make the entire
series of regulators easy to use and minimize the
number of external components. It is not necessary to
bypass the output, although this does improve
transient response. Input bypassing is needed only if
the regulator is located far from the filter capacitor of
the power supply.
LM7805 is also available in a higher accuracy and
better performance version (LM340A). Refer to
LM340A specifications in the LM340A Electrical
Characterisitcs table.

*Required if the regulator is located far from
the power supply filter.
**Although no output capacitor is needed
for stability, it does help transient response.
(If needed, use 0.1-μF, ceramic disc).
