TECHNICAL SPECIFICATIONS OF 3-TERMINAL NEGATIVE VOLTAGE REGULAT OR

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.
