The Texas Instruments LM117H/883 is a military-screened, adjustable positive linear voltage regulator housed in a hermetically sealed TO-39 metal can package. This device is capable of delivering in excess of 1.5 A to a load over an adjustable output voltage range, typically referenced to 1.25 V, and integrates internal current limiting, thermal overload protection, and safe-area compensation to ensure robust operation under demanding conditions. The “/883” suffix designates full compliance with MIL-STD-883 screening flows for monolithic microcircuits, guaranteeing extended temperature range performance and high reliability beyond standard industrial-grade equivalents.
Typical deployments include high-reliability power management in avionics, missile guidance systems, radar power supplies, and ruggedized field equipment where component failure is not tolerated. The TO-39 package offers a compact footprint with established thermal characteristics suitable for hostile environments. From a procurement standpoint, the MIL-PRF-38535 qualification and documented traceability associated with /883 products reduce counterfeiting risk but also imply longer lead times and mandatory source-control drawing requirements. Systems designed with this device should account for its non-low-dropout (non-LDO) architecture, which requires adequate input-output voltage headroom. Long-term availability is generally supported by the vendor’s military product roadmap, though periodic obsolescence reviews are advised to align with program life-cycle planning.
