TECHNICAL SPECIFICATIONS OF 3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
These regulators empoly internal current limiting and thermal
shutdown, making them essentially indestructible. They can
deliver over 1A output current with adequate heatsinking. 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.
