VOLTAGE REGULATOR, +5 VOLTS AT 1.0A
General Description
The LM140 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 1.0A 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.
