Radiation Hardened Adjustable Positive Voltage
Regulator
HS-117RH, HS-117EH
Features
The Radiation Hardened HS-117RH, HS-117EH are 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
• Electrically Screened to DLA SMD # 5962-99547
• QML Qualified per MIL-PRF-38535 Requirements
• Radiation Environment
- 300 krad (Si) (Max)
- Latch-up Immune
capable of sourcing from 5mA to 1.25A
(0.5 A for

the TO-39 package). Protection is provided by the on-chip
thermal shutdown and output current limiting circuitry.
• Superior Temperature Stability
The Intersil HS-117RH, HS-117EH has advantages over other
industry standard types, in that circuitry is incorporated to
minimize the effects of radiation and temperature on device
stability.
• Overcurrent and Overtemperature Protection
Applications
• Adjustable Linear Voltage Regulators
Constructed with the Intersil dielectrically isolated Rad Hard
Silicon Gate (RSG) process, the HS-117RH, HS-117EH are
immune to single event latch-up and has been specifically
designed to provide highly reliable performance in harsh
radiation environments.
• Adjustable Linear Current Regulator
Specifications for Rad Hard QML devices are controlled by the
Defense Logistics Agency (DLA). The SMD numbers listed here
must be used when ordering.
