The L7980 device is a step-down switching regulator with a 2.5 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 2 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/16972819/l7980atr-2-a-step-down-switching-regulator 2020-06-16 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2021-04-03 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2021-04-15 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2021-07-16 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2021-12-04 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2022-04-07 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2022-06-13 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2022-06-25 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2023-12-30 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2024-05-29 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-01-23 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-03-29 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-04-07 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-06-16 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-07-04 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-10-02 https://elecena.pl/product/16972819/l7980atr-2-a-step-down-switching-regulator 2025-10-21
