DC COMPONENTS CO., LTD. TECHNICAL SPECIFICA TIONS 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.
