The Ricoh R3111H271A-T1-FE is a voltage supervisory circuit from the R3111H series, manufactured by Ricoh Electronic Devices Company. This component is designed to monitor voltage levels and ensure system stability. It features a nominal threshold voltage of 2.9V, with an overvoltage threshold of 2.958V and an undervoltage threshold of 2.842V. The device operates with a supply voltage range from 0.7V to 10V and consumes a low operating current of 1.1 µA.
With an accuracy of 2%, the R3111H271A-T1-FE provides reliable voltage detection. It includes features such as backup battery switch and power fail detection, but lacks a manual reset and watchdog timer. The output type is CMOS, Open Drain. The operating temperature range is from -40°C to +85°C, making it suitable for various environmental conditions.
This supervisory circuit is housed in a SOT-89-3 package and is available in SMD/SMT mounting. The standard package quantity is 1000 units, supplied on tape and reel. Its primary function is to detect voltage drops or surges, protecting sensitive electronic equipment from unstable power conditions.
