The L5983 is a step-down switching regulator with a 2.0 A (min.) current limited embedded Power MOSFET, so it is able to deliver an output current in excess of 1.5 A DC to the load. The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN. Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus. 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 VFQFPN package with an exposed pad allows reducing the RthJAdown to approximately 60 °C/W. https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2020-06-04 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2021-04-03 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2021-04-15 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2021-07-13 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2021-12-04 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2022-04-11 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2023-12-30 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2024-08-16 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2024-11-20 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2025-01-23 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2025-06-16 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2025-07-04 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2026-05-05 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2026-05-24 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2026-06-03 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2026-06-21 https://elecena.pl/product/16942617/l5983tr-1-5-a-step-down-switching-regulator 2026-08-09
