The ADP3330 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3330 operates with an input voltage range of 2.9 V to 12 V and delivers a load current of 200 mA.
The ADP3330 is a precision low‑dropout (LDO) regulator offered by Analog Devices. It operates from 2.9 V to 12 V input and delivers up to 200 mA output current. Its architecture provides high accuracy (+0.7 % at 25 °C, +1.4 % over temperature), an ultralow dropout of 140 mV at 200 mA, and a shutdown current of less than 2 pA. The device is stable with any type of output capacitor (anyCAP), including MLCCs, and requires only a 0.47 µF capacitor for stability.
Typical applications include cellular phones, notebook computers, battery‑powered systems, PCMCIA regulators, barcode scanners, camcorders and other portable electronics. The datasheet also details thermal overload protection, current limiting, noise reduction options, and the patented Chip‑on‑Lead package that improves thermal performance in an SOT‑23‑6 footprint.
