The LM340-MIL monolithic 3-pin 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 regulator 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.
