Analog Devices ADP3333 Rev. B Datasheet
The ADP3333 Rev. B is a precision low‑dropout (LDO) regulator offering high accuracy (±0.8% at 25 °C) and low noise in an ultrasmall 8‑lead MSOP package. It operates from 2.6 V to 12 V supply voltage, delivers up to 300 mA load current, and requires only a 1.0 µF output capacitor for stability, making it suitable for space‑constrained applications such as cellular phones and PDAs.
The datasheet provides detailed specifications, absolute maximum ratings, pin descriptions, typical performance curves, theory of operation, and design guidance including capacitor selection, thermal overload protection, shutdown mode, PCB layout recommendations, outline dimensions and ordering information.
