DESCRIPTION
These negative regulators are supplied in a hermetically sealed 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 .5 amps of output current. These units feature internally trimmed output
voltages to ±1% of nominal voltage. Standard voltages are -5V, -12V, and -15V.
These units are ideally suited for Military applications where a hermetic surface
mount package is required.

Notes:
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. Short Circuit protection is only assured up to V
IN
= -35V.
3. If not tested, shall be guaranteed to the specified limits.
The • denotes the specifications which apply over the full operating temperature range.
4. Minimum load current for full line regulation = 5.0 mA.
