SG2813J/883B

The SG2813J/883B is a high-reliability low dropout positive voltage regulator from Microchip Technology, delivering a stable fixed output voltage with minimal input-to-output differential. As a member of the SG2800 family, it features internal current limiting, thermal shutdown protection, and a dropout voltage typically below 1.2 V at its full rated output current of 1.5 A. Housed in a ceramic dual-in-line (CDIP) package, the /883B suffix confirms compliance with MIL-STD-883 Class B screening, including 100% burn-in, temperature cycling, and hermetic seal testing for reliable operation across the full -55°C to +125°C military temperature range.

This regulator is suited for power conditioning in aerospace flight controls, defense radar and communication systems, and high-reliability industrial equipment requiring voltage stability and long-term dependability. The hermetically sealed CDIP package provides moisture resistance and mechanical ruggedness for extreme environments. Procurement teams should note the /883B designation guarantees military-grade pedigree with full lot traceability and qualification data, reducing qualification burden for programs using DSCC-standard parts. As a Microchip product, the SG2813J/883B benefits from continued manufacturer support, though design groups should monitor lifecycle status for long-duration programs to mitigate obsolescence risk. Standard export control classifications may apply.
