DESCRIPTION
These three terminal positive regulators are supplied in a hermetic metal surface
mount package. All protective features are designed into the circuit including thermal
shutdown, current limiting and safe-area control. With heat sinking, they can deliver
over 1.5 amps of output current. These units feature internally trimmed output
voltages to ±1% of nominal output voltage. Standard voltages are 5V, 12V, and 15V.
These units are ideally suited for Military applications where a hermetically sealed
surface mount package is required.
