Three Terminal Positive Regulators
General Description
The monolithic 3-terminal positive voltage regulators employ
internal current-limiting, thermal shutdown and safe-area
compensation, making them essentially indestructible. If ad-
equate heat sinking is provided, they can deliver over 0.5A
and 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 exter-
nal components. It is not necessary to bypass the output,
although this does improve transient response. Input by-
passing is needed only if the regulator is located far from the
filter capacitor of the power supply.
