The Radiation Hardened HS-117RH is an adjustable positive voltage linear regulator capable of operating with input voltages up to 40VDC. The output voltage is adjustable from 1.2V to 37V with two external resistors. The device is capable of sourcing from 5mA to 1.25APEAK (0.5 APEAK for the TO-39 package). Protection is provided by the on-chip thermal shutdown and output current limiting circuitry. The Intersil HS-117RH has advantages over other industry standard types, in that circuitry is incorporated to minimize the effects of radiation and temperature on device stability. Constructed with the Intersil dielectrically isolated Rad Hard Silicon Gate (RSG) process, the HS-117RH is immune to single event latch-up and has been specifically designed to provide highly reliable performance in harsh radiation environments.
