DESCRIPTION
This three terminal negative regulator is 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
1.0 amp of output current. This unit features output voltages that can be trimmed
using external resistors, from -1.2 volts to -37 volts.

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. If not tested, shall be guaranteed to the specified limits.
3. The
denotes the specifications which apply over the full operating temperature range.
