DESCRIPTION:
The MSK5979RH offers low dropout down to 300mV and an output voltage range down to zero volts while offering ra-
diation tolerance for space applications. This, combined with the low θJC, allows increased output current while providing
exceptional device efficiency. Because of the increased efficiency, a small hermetic 3 pin package can be used providing
maximum performance while occupying minimal board space. Output voltage is selected by the user through the use of 1
external resistor. Additionally, the regulator offers internal short circuit current and thermal limiting, which allows circuit pro-
tection and eliminates the need for external components and excessive derating.
