The ADuM1280 / ADuM1281 / ADuM1285 / ADuM12861 (also referred to as ADuM128x in this data sheet) are dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices and other integrated couplers.
1. General-purpose multichannel isolation 2. Data converter isolation 3. Industrial field bus isolation 4. Hybrid electric vehicles, battery monitor, and motor drive
The function of this semiconductor is Positive voltage regulators.
Manufacturers : STMicroelectronics
The L78L series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or oncard regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The L78L series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise.
1. Output current up to 100 mA 2. Output voltages of 3.3 V thermal overload protection 3. Short-circuit protection 4. No external components are required
