Analog Devices ADP3331 Low‑Dropout Regulator Datasheet
The ADP3331 is a precision low‑dropout (LDO) regulator from Analog Devices. It operates from 2.6 V to 12 V input and provides an adjustable output from 1.5 V to 11.75 V, delivering up to 200 mA with typical 140 mV dropout at full load. The device is stable with a single 0.47 µF output capacitor and is tolerant of any capacitor ESR, thanks to its patented anyCAP technology.
The datasheet includes detailed specifications, typical performance graphs, theory of operation, and design guidelines such as capacitor selection, noise reduction, thermal management, and PCB layout. It also describes protection features like current limiting, thermal shutdown, and an error‑flag output for pre‑emptive regulation loss detection.
