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

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.
