The ADP3338 is a mems-based, high accuracy, ultralow IQ, 1 A, anyCAP® low dropout regulator. It has a high accuracy, ultralow dropout, low noise, wide operating temperature range, SOT-223 package, etc.
The ADP3338 is a precision low‑dropout (LDO) regulator that operates from 2.7 V to 8 V and delivers up to 1 A of load current. It offers high accuracy (0.8 % at 25 °C), ultralow dropout (190 mV typ at 1 A), low noise, and built‑in current‑limit and thermal‑overload protection, making it suitable for notebook computers, battery‑powered systems, and other portable applications.
The datasheet provides detailed specifications, absolute maximum ratings, pin configuration, typical performance curves, and application guidelines. The device is supplied in an SOT‑223 package and requires only a 1 µF output capacitor for stability, with no sensitivity to capacitor ESR.
