This document is about ADP3334 high precision low IQ anyCAP adjustable low dropout regulator. It introduces the features and characteristics of this regulator, including high accuracy, low IQ, low dropout voltage, adjustable output voltage and so on.
The ADP3334 from Analog Devices is a precision low‑dropout (LDO) regulator offering high accuracy over line, load and temperature. It operates from a 2.6 V to 11 V input range and can deliver up to 500 mA continuous current. The device uses the patented anyCAP architecture, allowing stable operation with any type of output capacitor, including low‑ESR ceramic MLCCs.
The datasheet provides detailed electrical specifications, package options (LFCSP‑8, MSOP‑8, SOIC‑8), thermal management guidelines, and design equations for setting the adjustable output voltage. It also includes absolute‑maximum ratings, ordering information, and revision history for engineers designing with the part.
