The L7981 device is a step-down switching regulator with a 3.7 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 3 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 28 V, while the output voltage can be set starting from 0.6 V to VIN. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz. The QFN and the HSOP packages with exposed pad allow reducing the RthJAdown to 60°C/W and 40°C/W respectively. https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2020-06-12 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-04-03 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-04-15 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-07-16 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-07-25 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-08-11 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2021-12-04 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2022-04-07 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2022-06-13 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2022-06-25 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-08-09 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-08-16 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-08-20 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-09-02 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-09-23 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-10-01 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-11-04 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-11-13 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-11-21 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-12-13 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2023-12-22 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-02-02 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-02-11 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-02-28 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-04-15 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-04-24 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-05-03 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-05-20 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-06-07 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-06-16 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-06-24 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-07-12 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-11-03 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-11-11 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2024-12-18 https://elecena.pl/product/16964240/l7981a-3-a-step-down-switching-regulator 2026-08-19
