distribution problems associated with single point regulation with single point regulation. In addition, they can be used with power pass elements to make high current
voltage regulators. If adequate heat sinking is provided, each of these regulator can deliver over 1A of output current. Although designed primarily as fixed
voltage regulators, these devices can be used with external components to obtain adjustable
voltage and currents.
FEATURES
◇ Output current up to 1A ◇ No external components required ◇ Internal short circuit current limiting ◇ Intermal thermal overload protection ◇ Output transistor safe-area compensation ◇ Output
voltage offered in 4% tolerance
