DESCRIPTION:
The MSK 5940RH is a fixed, radiation hardened, negative voltage regulator which offers low dropout and output voltage
accuracy to ±1% maximum. The low θjc combined with low dropout allows increased output current and excellent device
efficiency. The MSK 5940RH offers both internal current limit and thermal overload protection. The case of the device
is electrically isolated for heat sinking purposes. The device is packaged in a space efficient 3 pin power package with
various lead form options. The MSK 5940RH series is also available in a power package with a top tab to accomodate direct
mounting to a heat sink.
