INTEGRATED CIRCUIT
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 up to 100mA output current, if the case temperature
o
can keep in T
C
=25 C. 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, they can be
used with power pass elements to make high-current voltage
regulators.
