AP1117 is a low dropout positive adjustable or fixed-mode regulator with features such as maximum 1.4V dropout at full load current, fast transient response, output current limiting, built-in thermal shutdown, etc.
The AP1117 regulator from Anachip provides a low‑dropout solution for low‑voltage ICs, offering both adjustable and fixed output versions (1.5 V, 1.8 V, 1.9 V, 2.5 V, 3.3 V, 5.0 V). It supports up to 1 A output current and operates with an input range from –0.3 V to 12 V.
Typical applications include PC peripherals, communication devices, VGA cards, and other low‑voltage logic supplies. The device features fast transient response, output current limiting, built‑in thermal shutdown, and good noise rejection, and is available in several packages such as SOT‑223, TO‑263, TO‑252, TO‑220, and SOT‑89.
