DESCRIPTION
This device offers a positive and negative adjustable regulator in one hermetically sealed 6-pin
surface mount package. All protective features are designed into the circuit, including thermal
shutdown, current limiting, and safe-area control. With heat sinking, these devices can deliver
up to 1.5 amps of output current. This device is ideally suited for military applications where
small size and high reliability is required.
