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.

Notes for both Positive and Negative Regulators Characteristics:
1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The
•denotes the specifications which apply over the full operating temperature range.
