Circuit adds foldback current protection

Circuit adds foldback-current protection

For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor’s LM317, offer ease of use, low cost, and full on-chip overload protection. The addition of a few components can provide a three-terminal regulator with high-speed short-circuit current limiting for improved reliability. The current […]

TINY MICROSUPERCAPACITOR THAT COULD POWER FUTURE WEARABLES

TINY MICROSUPERCAPACITOR THAT COULD POWER FUTURE WEARABLES

A group of researchers from the Ulsan National Institute of Science and Technology (UNIST), South Korea, have designed a really tiny and ultra-dense Micro-supercapacitor that can be printed directly into circuits. Microsupercapacitors (MSCs) have garnered considerable attention as a promising power source for microelectronics and miniaturized portable/wearable devices. However, their practical application has been hindered by the manufacturing
