TECHNICAL SPECIFICATIONS OF LOW CURRENT 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
can keep in TC=25oC. 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.
