The LD39100 provides 1 A maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV. The device is stable with ceramic capacitors on the input and output. The ultra-low dropout voltage, low quiescent current and low-noise features make it suitable for low power battery-powered applications. Power supply rejection is 70 dB at low frequency and starts to roll off at 10 kHz. Enable logic control function puts the LD39100 in shutdown mode, allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection. LD39100 is available also in AEC-Q100 qualified version, in the DFN6 (3x3 mm) with wettable flank package. https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2020-06-04 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2021-04-15 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2021-07-16 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2021-12-04 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2022-04-07 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2022-06-12 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2022-06-25 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2023-12-05 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2024-04-24 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2024-07-30 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2024-08-17 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2024-11-21 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-01-23 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-06-16 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-07-05 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-08-20 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-09-17 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2025-10-21 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-05-15 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-05-24 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-07-11 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-08-09 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-08-19 https://elecena.pl/product/16940841/ld39100pu25ry-1-a-low-quiescent-current-low-noise-voltage-regulator 2026-08-29
