The ST1S31 device is an internally compensated 1.5 MHz fixed-frequency PWM synchronous step-down regulator. The ST1S31 operates from 2.8 V to 5.5 V input, while it regulates an output voltage as low as 0.8 V and up to VIN. The ST1S31 integrates a 60 mΩ high-side switch and a 45 mΩ synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with internal compensation delivers a very compact solution with a minimum component count. The ST1S31 device is available in 3 mm x 3 mm, 8 lead VFDFPN and SO8 packages. https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2020-06-26 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2021-04-03 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2021-04-15 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2021-07-16 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2021-12-04 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2022-04-07 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2022-06-13 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2022-06-25 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2023-03-23 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2023-05-19 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2023-12-13 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-02-11 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-04-24 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-05-20 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-06-07 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-06-16 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-06-24 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-07-12 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-07-21 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-09-12 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-10-07 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-10-16 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-10-25 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-11-11 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-11-20 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2024-12-27 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-01-14 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-01-23 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-02-01 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-02-11 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-02-20 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-03-29 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-04-07 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-05-04 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-05-19 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-06-16 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-07-04 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-10-12 https://elecena.pl/product/16991124/st1s31pur-3-a-dc-step-down-switching-regulator 2025-10-30
