The ADP3331 is a high accuracy, low dropout, adjustable output, ultralow IQ, 200mA, SOT-23, anyCAP ® low dropout regulator.
The ADP3331 is a precision low‑dropout regulator with an input range of 2.6 V to 12 V and an adjustable output from 1.5 V to 11.75 V, delivering up to 200 mA. It offers ultralow dropout (140 mV typ. at 200 mA), low quiescent current, and a shutdown current of less than 10 nA.
The document includes detailed specifications, functional block diagrams, theory of operation, layout recommendations, and guidance for capacitor selection, thermal management, and higher‑current configurations. It also describes the patented Chip‑on‑Lead SOT‑23‑6 package that enhances thermal performance.
