San Diego-based Express Logic just received IEC 61508 and IEC 62304 certification for its ThreadX operating system. These two standards cover the “functional safety of electrical, electronic, and programmable electronic safety-related systems.” The nice part is, the certification is for bone-standard ThreadX; there is no special “safety-certified” version of the RTOS. Express Logic says it won’t even charge more, now that it’s certified.
 Five Things You Should Know About Linear RegulatorsSponsored by Maxim Integrated While linear regulators (LDOs) seem relatively simple, many situations occur in which LDOs perform contrary to your expectations. This application note explores five of those situations, including startup, quiescent current near dropout, load transient performance, PSRR and noise, and input protections. Understanding these situations will improve product selection and debug processes. |
