The ADP3333 is a precision low dropout (LDO) any CAP voltage regulator with high accuracy, ultralow IQ and 300mA of output current.
The ADP3333 is a high‑accuracy, ultra‑low dropout (LDO) regulator that operates from 2.6 V to 12 V and delivers up to 300 mA. It features a novel anyCAP architecture that requires only a 1 µF output capacitor for stability and is tolerant of any capacitor type, including MLCCs. The device offers ±0.8 % voltage accuracy at room temperature, low noise, and built‑in current‑limit and thermal‑shutdown protection.
The datasheet provides detailed specifications, pin descriptions, ordering information, and design guidelines such as capacitor selection, PCB layout recommendations, and thermal calculations. It also includes typical performance graphs and a functional block diagram to aid designers in integrating the regulator into portable and space‑constrained applications.
