The AP2204 is a low‑dropout regulator with a 2.3 V‑24 V input range, multiple fixed/adjustable outputs, and SOT‑23‑5, SOT‑89, PSOP‑8 packages.
The AP2204 series is a positive‑voltage ULDO regulator designed for USB and portable devices. It offers a wide input voltage range, low dropout, low quiescent current, and built‑in current limiting and thermal shutdown.
The device is available in fixed‑voltage versions (1.5 V to 5 V) and an adjustable version, packaged in space‑saving SOT‑23‑5, SOT‑89, or PSOP‑8. Detailed electrical characteristics, ordering information, and mechanical dimensions are provided for designers.
